the act of disrespecting ones couch

What Rick James or Dave Chappelle would say when he kills someone.

This phrase was brought into prominence and popularized by Chappelle's Show in episode #204, where Rick James says "fuck yo couch, nigga" when he is caught kicking mud on Charlie Murphy's white couch.

The phrase entered pop culture lexicon to mean audacious contempt, discontent or disregard for a given standard, convention or ideal, or utter indifference to a given situation.

When there is nothing left to say to someone else (In a shit talking manner, or you just run out of reasons for an argument) you say this.
(Better used when talking to azn people....)

when you get really mad at someone and you dont know what else to say.

A phrase one uses to convey that one does not desire to receive any of someone else's stuff.
