co-bang 

When you and your boy smash out another chick at the same time (preferably in different orifices).

Kurt Cobang 

A funny way to refer to Kurt Cobain, a lame musician who blew his head off with a shotgun, presumably making the sound "co-bang" in the process.

Kurt Cobang is no more. He blasted his head apart with a shotgun. When he did it, it went "Bang!" That was pretty smart of him to do that. He made a big nasty mess, too.
