You’re scrolling through Instagram, half-asleep, when you see a comment that says, “Nah, that’s cap.” Or maybe a friend texts you, “No cap, I’m serious.” You pause. Cap? Like a hat? A bottle cap? Clearly not.
If you’ve ever seen “cap” in a text, TikTok caption, or group chat and felt slightly confused, you’re not alone.
This slang word blew up online and now pops up everywhere—from casual chats to viral memes.
In this guide, we’ll break down what does cap mean, how people actually use it, and whether it’s friendly, flirty, or totally casual.
Quick Answer:
In slang and texting, “cap” means a lie or something untrue.
When someone says “that’s cap,” they mean “that’s fake” or “you’re lying.”
“No cap” means no lie or I’m being honest.
The term is popular on social media, texting, and Gen Z slang.
What Does Cap Mean in Text?
In texting and online slang, “cap” means a lie or something that’s not true.
