If you have spent time scrolling through TikTok comments, you may have come across the phrase “4th hole” and wondered what everyone is talking about. The phrase often appears in jokes, comments, memes, and reaction videos, usually without any explanation. That can make it especially confusing if you have never encountered the slang before.
So, what is the 4th hole slang on TikTok?
The phrase “4th hole” is an adult internet slang term used as a sexual joke or euphemism involving female anatomy. It is not a recognized medical term, and there is no officially named anatomical structure called the “fourth hole.” Instead, the expression became part of online meme culture and is often used to confuse people, create shock humor, or make a suggestive joke.
The phrase became particularly popular across social media after people began discussing the idea online, and TikTok helped push it into a much wider audience.
Quick Answer: What Does 4th Hole Mean on TikTok?
“4th hole” on TikTok is usually a sexual joke or internet meme referring to a supposed additional body opening.
It is not a real medical term. People generally use the phrase for humor, sexual innuendo, or to deliberately confuse someone who has never heard the meme.
You might see comments such as:
“Wait until you hear about the 4th hole 💀”
or:
“Bro just discovered the 4th hole 😭”
In most cases, these comments are not meant to provide factual information. They are referencing an internet joke.
The phrase can also be used differently from one TikTok to another, which is why you may find slightly different explanations online.
What Does “4th Hole” Mean in Slang?
In slang, “4th hole” is generally an adult-oriented sexual reference. The joke is based on the idea of a mysterious additional opening that people supposedly don’t know about.
The humor comes partly from making the phrase sound like an ordinary fact.
Someone might confidently say:
“You don’t know about the fourth one?”
The other person may immediately wonder:
“Fourth what?”
That confusion is exactly what makes the joke work.
Rather than being a serious anatomical term, the fourth hole is primarily an internet meme. People may use it in comments simply because they know that other users will recognize the reference.
Is the 4th Hole Actually Real?
No, “the 4th hole” is not a standard anatomical term.
This is probably the most important thing to understand about the trend.
Social media jokes sometimes present fictional or exaggerated information as though it were a secret fact. The “4th hole” meme uses that exact idea. Someone may make the statement confidently enough that another person starts questioning whether they missed something in biology class.
The phrase should therefore not be treated as medical information.
If you are looking for accurate information about human anatomy, use proper anatomical terminology and reliable educational or medical sources rather than viral TikTok slang.
Why Does It Sound So Believable?
The phrase is effective because it sounds surprisingly straightforward.
When someone says:
“There are four.”
your brain naturally wants to know what the four things are.
The joke then creates a small moment of confusion before revealing, or hinting at, the sexual meaning.
That combination of mystery + embarrassment + humor is one reason the phrase works so well as an internet meme. 😂

Where Did the 4th Hole Meme Come From?
The idea did not originate exclusively on TikTok.
The joke has an older connection to the animated television series Family Guy, where the character Glenn Quagmire makes a humorous reference to a supposed fourth opening. The scene later became part of the wider internet’s meme culture.
Years later, the concept resurfaced online and gained significant attention through social media discussions. People began debating what the supposed “fourth hole” was, and the confusion itself helped the joke spread.
Eventually, the phrase found its way into TikTok videos and comments, where it became easier for millions of users to encounter it.
This is a good example of how old jokes can become new slang when they are rediscovered by a different generation of internet users.
Why Is the 4th Hole So Popular on TikTok?
TikTok is particularly good at turning confusing phrases into viral trends.
A creator does not need to explain the entire joke. They can simply say:
“Wait until they find out about the 4th hole.”
Someone unfamiliar with the reference may immediately ask:
“What is the fourth hole?”
That question creates engagement.
Other users then respond with jokes, memes, emojis, or deliberately misleading explanations. Before long, more people encounter the phrase and search for its meaning.
In other words, the confusion becomes part of the entertainment.
This is common with TikTok slang. Some phrases become popular because they communicate something useful, while others become popular because people enjoy watching newcomers try to figure them out.
What Does “4th Hole” Mean in TikTok Comments?
If you see “4th hole” in a TikTok comment, the commenter is usually making an adult joke or referencing the meme.
For example:
“She knows about the 4th hole 💀”
This is not normally a literal statement about anatomy. It is a reference to the internet joke.
Another person might comment:
“Bro found the 4th hole 😭”
Again, the purpose is usually humor rather than factual discussion.
Sometimes people deliberately post these comments under unrelated videos simply because they know other users will recognize the reference.
Why Do People Use “4th Hole” as a Joke?
There are several reasons the phrase works so well online.
First, it sounds like something that should be factual. Secondly, it involves an embarrassing subject, which makes people react strongly. Finally, it is vague enough that users can keep the joke going without explaining it directly.
That combination makes the phrase perfect for comment sections.
Someone can mention the “4th hole” and allow other users to fill in the meaning themselves.
This type of humor is especially common online because people enjoy jokes that make newcomers feel temporarily confused while longtime users understand the reference.
Is 4th Hole a Sexual Term?
Yes, in most TikTok and meme contexts, it has a sexual meaning.
The phrase is generally used as sexual innuendo, rather than as a neutral expression.
That does not mean every appearance of the words is automatically sexual. Someone could theoretically use “fourth hole” in a completely unrelated context, such as golf or another subject.
But when you see “4th hole” in TikTok slang, memes, or comments about relationships and anatomy, the adult joke is usually what the person is referencing.
Is the 4th Hole Slang Appropriate?
Because the expression commonly has a sexual meaning, it is not appropriate for every situation.
It may be used casually between adults who understand the joke, but it would be out of place in a professional conversation, classroom, or family-friendly setting.
There is also an important difference between understanding slang and using slang.
You may want to know what someone means when they use “4th hole” without ever using the phrase yourself.
That is perfectly normal, especially when you’re trying to understand something you saw in a TikTok comment.

What Does “All 4 Holes” Mean?
Another phrase you may encounter online is “all 4 holes.”
This comes from the same general meme and is used as a sexual joke.
The wording is deliberately vague, which allows people to joke about it without directly explaining what they mean.
You may see someone write:
“He said all 4 💀”
or:
“Not the all 4 holes comment again 😭”
These comments are usually references to the same viral internet joke.
The important thing is that “all 4 holes” should not be interpreted as a scientific description of anatomy.
Why Are People Confused About the Fourth Hole?
The confusion is actually one of the main reasons the meme became popular.
Imagine someone tells you:
“Everyone knows about the fourth hole.”
If you have never heard the joke, your immediate reaction may be:
“Wait… what fourth hole?”
That reaction gives the person an opportunity to continue the joke.
They may refuse to explain it, give an absurd answer, or simply respond with laughing emojis.
This creates a classic internet bait-and-reaction format.
The person who already knows the meme gets entertainment from watching someone else become confused.
The 4th Hole vs. Actual Anatomy
It is important to separate the meme from real anatomy.
The human body has established anatomical structures with specific names and functions. “Fourth hole” is not the standard medical name for an additional female anatomical opening.
When TikTok creators use the term, they are generally participating in a joke rather than teaching biology.
This distinction matters because viral content can sometimes sound authoritative even when it is completely unserious.
In Simple Terms
4th hole slang: Internet joke and sexual meme.
Medical terminology: Scientific language used to describe actual anatomy.
They are not the same thing.

What Does 4th Hole Mean for Girls?
Online discussions about the phrase usually connect the joke with female anatomy, which is why the expression is often mentioned in conversations involving women.
However, the phrase should not be interpreted as an actual anatomical discovery.
The “fourth hole” idea is essentially a meme built around misinformation-style humor. People pretend there is a secret fact that everyone else somehow failed to learn.
That is why someone may jokingly tell another person:
“How did you not know about the fourth one?”
The humor comes from pretending that the listener is missing some obvious piece of information.
Does the 4th Hole Have a Different Meaning From the 3 Holes?
You may see TikTok users discussing the supposed “three holes” and then introducing a “fourth.”
This is simply part of the joke’s setup.
The meme takes an actual discussion about anatomy and adds a fictional or humorous fourth element to create confusion.
Because the joke is often presented without context, people who encounter it for the first time may genuinely think the discussion is educational.
It is not.
The “4th hole” phrase is internet slang, not a medical lesson.
Is the 4th Hole Slang Only Used by Teenagers?
Not necessarily.
Internet slang can be used by people of different ages, especially when a meme becomes widespread.
However, the phrase is strongly associated with social media and online meme culture, so you’re more likely to encounter it on platforms such as TikTok, Instagram, X, Reddit, Discord, or similar communities than in ordinary face-to-face conversation.
The meaning also depends on whether the person knows the meme.
Someone who has never encountered it may simply think you are talking about a literal hole.
Examples of 4th Hole Slang in Texts and Comments
Understanding examples makes the slang much easier to recognize.
Example 1
“Wait, you don’t know about the 4th hole? 😭”
This is usually someone teasing another person who has not heard the meme.
Example 2
“Bro discovered the 4th hole 💀”
This is a humorous reference to the viral joke.
Example 3
“Not the 4th hole comments again 😂”
Here, the person recognizes the recurring meme in a comment section.
Example 4
“She knows about all 4 💀”
This is another variation of the same adult joke.
The wording can change, but the sexual meme reference usually remains the same.
Is 4th Hole a Dirty Word?
The phrase itself is not technically a swear word.
However, because it is commonly used as sexual slang, it can be considered crude or inappropriate depending on the context.
It is similar to many internet euphemisms: the words themselves may sound harmless, but the intended meaning can be adult-oriented.
For example, someone might use the phrase jokingly among friends but avoid saying it in a professional environment.
Can “4th Hole” Be Used in a Normal Conversation?
Technically, the words “fourth hole” can obviously be used in ordinary situations.
For example:
“The fourth hole on the golf course is difficult.”
That has nothing to do with TikTok slang.
The slang meaning appears when the phrase is used in the specific internet meme context.
Therefore, you should always consider the topic before interpreting the phrase.
If someone is talking about golf, it is probably a golf hole.
If someone is talking about TikTok, anatomy, dating, or sexual jokes, the meme meaning is much more likely.
Why Internet Slang Can Be Misleading
The “4th hole” trend is a good example of how quickly online language can become confusing.
A phrase can begin as a joke, become a meme, and then be repeated so often that new users assume it is a genuine expression.
Eventually, someone may search for its definition and discover dozens of conflicting explanations.
That does not necessarily mean the slang has a complicated history.
Sometimes the joke itself is the explanation.
The phrase is intentionally confusing because confusing people is part of the entertainment.

Common Misconceptions About the 4th Hole
One common misconception is that TikTok discovered a previously unknown part of female anatomy. It did not. The phrase is a meme.
Another misconception is that every person who says “4th hole” is talking about the exact same thing. Internet users sometimes modify memes or create their own variations, so the wording can have slightly different meanings.
It is also incorrect to assume that the phrase originated entirely on TikTok. TikTok helped spread it, but the joke has older roots in internet and pop culture.
Why the 4th Hole Meme Keeps Coming Back
Internet memes rarely disappear completely.
A phrase may become popular, fade away, and then return when a new generation of TikTok creators discovers it.
The “4th hole” joke has exactly the kind of structure that makes this possible. It is short, easy to type, easy to explain through reactions, and naturally creates curiosity.
A creator does not need to make an entire video about it. One sentence in a comment can be enough to revive the joke.
That’s why you may suddenly see “4th hole” everywhere even though you had never heard it before.
What Should You Do If Someone Says “4th Hole” to You?
If someone uses the phrase and you are unsure what they mean, you can simply ask:
“What do you mean by 4th hole?”
If they are referencing the meme, they will probably explain it or laugh.
You do not need to assume that the phrase is factual, and you certainly do not need to repeat it if you are uncomfortable with sexual jokes.
Understanding internet slang is useful because it helps you recognize what people mean, but you don’t have to participate in every trend you understand.
