Something yelled out by a Call Of Duty online multiplayer when he kills another player using his knife, tactical knife, or throwing knife. Of course this is referring to O.J. Simpson brutally murdering his ex wife Nicole Brown Simpson and her friend Ronald Goldman with a knife in 1994. It also refers to a comedy skit by Dave Chappelle in which people yell out a sports star’s name prior to duplicating a heinous or despicable act they are famous for committing.

Nerd 1: Hah, Hah! You like Orgasm Juice!
Nerd 2: Screw you! At least I can get some!
