Some who, while playing halo-like games, will constantly get kills with randomly thrown grenades. Mostly by luck; in fact one could say that there is no skill involved.
Player: Hey, I just got killed by a 'nade.
Grenade Bitch: Oh yeah I just threw that.
Player: Did you know I was there.
Grenade Bitch: Why would I need to know you were there?
Grenade Bitch: Oh yeah I just threw that.
Player: Did you know I was there.
Grenade Bitch: Why would I need to know you were there?
