A Halo 2 term. It is simply when you are at point blank range with your opponent and you blast him in the face with a shotgun. It gets his name from Nirvana lead singer Curt Cobain who blew his head off with a shot gun.
I was playing some noob yesterday, and he accually was pathetic enough to let me get him with a Reverse Cobain!
