Meaning & Definition of Cap Slang 🧢
In modern slang, “cap” means a lie, an exaggeration, or a boastful claim. When someone says “that’s cap,” they’re calling out a statement as false. The cap slang meaning centers on dishonesty, whether it’s a small stretch of the truth or a full-blown lie.
“No cap” flips the meaning entirely. It signals sincerity, similar to saying “I swear” or “for real.” Together, these two phrases form one of the most recognizable slang pairs online today.
Secondary meanings
- Bragging or boasting — an older use tied to “talking big.”

- A unit of time (roughly 20 minutes) in some casual chats.
- A literal headwear item, unrelated to the slang use.
What does cap stand for
Cap doesn’t stand for an acronym. It’s a standalone slang word, not shorthand for a phrase. The cap slang meaning comes from cultural usage, not letter-by-letter meaning. People sometimes assume it’s an abbreviation, but it isn’t.
Stop the cap meaning
“Stop the cap” is a direct way of telling someone to stop lying or exaggerating. It’s a firmer version of just saying “cap.” People use it when a claim feels obviously untrue or over the top.
