Part of the reason the phrase became so popular is because it creates curiosity. People see references to a mysterious “fourth hole” and start searching for answers. As more users ask questions, the trend spreads even further.
The meaning of “4th hole” varies depending on the conversation. Some people use it as a joke, others use it in anatomy discussions, while some internet communities have created entirely different interpretations. Because of these multiple meanings, the phrase has become one of TikTok’s most confusing slang terms.
In this guide, you’ll learn what the 4th hole slang means on TikTok, where it came from, how people use it online, common examples, and why it became such a viral internet trend.
What Does “4th Hole” Mean on TikTok?
The most common TikTok meaning of “4th hole” refers to discussions about body anatomy and the idea that there is an additional body opening that many people don’t usually think about. In many TikTok videos, users identify the “4th hole” as the urethra during anatomy-related conversations and jokes.
However, the phrase is rarely used in a serious educational context.
Instead, TikTok creators often mention it in:
- Comedy videos
- Meme content
- Reaction videos
- Viral discussions
- Shock-value content
- Anatomy misconceptions
Many viewers discover the term through humorous videos rather than educational content.
Why Is It Called the 4th Hole?
The phrase comes from online discussions where users count different body openings and debate what qualifies as the “fourth” one.
This led to countless arguments, jokes, and memes because not everyone agreed on the answer. Different creators offered different explanations, which only increased confusion and engagement.
As often happens on social media, the confusion became part of the joke.
People started intentionally giving ridiculous answers such as:
- The ear
- Behind the knee
- The belly button
- A secret hidden hole
- A metaphorical hole
Many users weren’t trying to provide accurate information. They simply wanted to keep the joke going.
The Family Guy Connection
One reason the phrase gained attention online is because many internet users traced it back to a joke from the animated television show:
Family Guy
In one episode, the character Glenn Quagmire jokes that women have a mysterious fourth hole. Years later, internet users rediscovered the joke and began sharing clips and memes based on it. The reference eventually spread across TikTok, X, Reddit, and Instagram.
Many younger users encountered the phrase through memes without realizing its connection to the television show.
Why Did the 4th Hole Go Viral?
Several factors contributed to its popularity.
1. Curiosity
People naturally want answers when they see something confusing.
A comment saying:
“She knows about the 4th hole.”
creates immediate curiosity.
Users often search the phrase simply because they want to understand the joke.
2. Engagement
TikTok’s algorithm rewards content that keeps people watching.
When users don’t understand something, they often:
- Rewatch videos
- Read comments
- Search for explanations
- Share content with friends
All of these actions increase engagement.
Some internet users even believe the phrase became popular specifically because it encourages viewers to spend more time interacting with content.
3. Meme Culture
Internet humor often thrives on absurdity.
The less sense a joke makes, the more likely people are to share it.
The 4th hole trend perfectly fits this pattern.
Alternative Meanings of the 4th Hole
One reason the slang remains confusing is that different communities use different meanings.
Anatomy Discussions
Many TikTok users use the term in anatomy-related conversations and identify a specific body opening as the fourth hole.
Meme Interpretations
Many creators intentionally avoid giving serious answers.
Examples include:
- The hole in your wallet
- The hole in your soul
- The hole behind your knee
- The hole in a tree
- A secret hidden opening
These joke answers became almost as popular as the original explanation.
Social Media Humor
Some users simply use the phrase as a random meme without caring about its actual meaning.
In these cases, the joke is that nobody knows what the 4th hole really is.

Why Do People Keep Arguing About It?
Most slang terms have a clear definition.

The internet never reached complete agreement on what it means.
Instead, users created multiple explanations and treated the confusion itself as part of the joke.
This endless debate keeps the trend alive.
Every time a new creator discusses the phrase, the argument starts again.
Is the 4th Hole a Real Anatomical Term?
No.
The phrase is internet slang.
It is not an official medical or scientific term.
Although some users discuss anatomy when explaining it, the phrase itself comes from internet culture rather than medicine.
This distinction is important because many people mistakenly assume it is a genuine anatomical concept.
Why Is the Term Controversial?
Some people view the phrase as harmless internet humor.
Others believe it can become inappropriate depending on the context.
The controversy exists because:
- It often involves body-related discussions.
- Many videos use suggestive humor.
- Different communities interpret it differently.
- Younger audiences frequently encounter the term without understanding it.
Because of this, discussions about the 4th hole often spark debates about internet slang and social media culture.
