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 coldcock 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.
