the act of destroying someones mental psychee by intentionally disregarding a joke/statement/funny comment; this involves ridiculing and shaming, as well as a potential loss of friendship
Hey Garrett, you just got fuckin' cold cocked...go rape a girl why don't you?
It is when you walk into someone and hit them hella hard, but you can`t just cold cock someone whenever according to the rules of engagement they have to be walking towards you and they can still dodge your coldcock if they spot it early enough.
