My 360 gt is MikeyJ92
On PC for fps matches like HL2: Deathmatch I go by Mikey, Beowulf or Jesus' Poop.
Like JKL, I and others get a kick out of it when the screen says:
Player 1 was humiliated by Jesus' Poop
Juvenile? Of course. But funny.
Plus sometimes I just like to act like a 13 year old online. It gets tiresome always being the one upstanding respectful anonymous player online...
