UMP j00

1. when a player in CounterStrike is killed by the suckiest submachinegun, his killer says: UMP j00!
2. At the start of a game of CS a player who buys the UMP submachinegun calls out: UMP J00! to put fear in the hearts of his opponents!

Me: UMP j00 N00BS!
N00b1: OMG I R UMPED!
N00b2: OMG ME TO
