To do something so bold simply to be an asshole. The phrase began on an episode of Dave Chappelle, in which Rick James utterly destroyed Eddie Murphy's couch, causing Eddie and his brother, Charlie Murphy to completely pwn Rick by the way of a beatdown administered to his legs.

An exclamation made when your friends or family are teasing you to a point where you can't handle it anymore and a hissy fit is in order.

Derived from a YouTube user's famed outburst following Britney's lackluster performance at the 2007 VMA's.

The insult to beat all insults in an argument, due to its pure randomness. Also tends to make the opponent speechless.

It's a metaphor. the "fuck" is metaphorical for not giving a shit, and the "your couch" is metaphorical as it is the subject that the user choses instead of the person it is being used against, thus making it clear that it is more important to the user than the recipient, and by not giving a shit about something that is more important to the user than the recipient, the user is saying that he or she less than gives a shit about about the recipient and anything they have ever said or done

From Chappelle's Rick James episode. Best used when the person you are saying it to is in a better situation then yourself.

pretty self explanitory but can be used in many ways....
