cappin

Within the context of cussing out someone, out-talking/smarting them; all in the sense to make them look stupid or wrong. Literally "restrains" them from having anything else to say.

Origin:

(1) Cappin like a bottle cap, shuttin you up.
(2) Breakin yo legs, handi"cappin" yo ass, you is now defenseless, can't do any other shit.

Person 1: The fuck am i writin for a large audience for? Like where the fuck would I have tried to name my friends in defining this definition and shit?
Person 2: Dude, why are you tryin to cap on Urban Dictionary? Stop cappin on em.
