Meaning & Definition of the 4th Hole Slang on TikTok

At its core, the 4th hole slang on TikTok is a suggestive, humorous, and intentionally ambiguous phrase. Unlike traditional slang that has a clear dictionary definition, this term operates on implication rather than explanation.

• A playful innuendo Copy
• A teasing reference to something “extra” or “beyond the obvious” Copy
• A bait phrase designed to provoke curiosity and comments Copy
• A way to hint at adult humor without explicit language Copy

The power of the phrase lies in the fact that it is never clearly defined. People use it knowing that others will ask questions like:
