I came up with it and it stuck
Especially when I started pulling name-appropriate stunts in games. One SE3 (hotseat) game I came from behind and won in 5 turns by blowing up all the other player's stars.. at the same time. One turn he's kicking my ***, the next he's down to his war fleet only with all his planets in cinders. Cloacking is good.
The other nick I use is Stalker-D (see a pattern yet? :P) but I only use it in games where I feel like playing with people's heads (CounterStrike, newbies with AWPs on the other team. Me with a knife, FF on. muwaahaa..) since people make lame jokes out of it too often.
