no cap.
“Honestly,” “for real,” or “I am not exaggerating.” Cap means a lie or an exaggeration in this slang context.
What does no cap mean?
No cap strengthens the truth claim in a statement. “That was the best meal this week, no cap” means the speaker wants the praise taken seriously rather than as casual exaggeration. It can appear at the beginning or end of a sentence.
Cap is the opposite idea: a lie, an exaggeration, or a claim someone does not believe. “That is cap” challenges what was said. Neither expression proves who is right; both communicate the speaker’s stance. The literal meaning of a hat is unrelated to this use, and a cap emoji can sometimes stand in for the slang word.
