Gotta be GB.
All of these other nominees have you all patting them on the back in a big troll circle-jerk. GB is the only person who has managed to piss off, irritate and annoy everyone here to the point of distraction without pulling lame death pranks or faking suicide. All he does it post words, and it drives even the most (self-)celebrated TK trolls to distraction on more than one board. He's owned you all, and you still won't recognize it because it's too painful to contemplate.
Well played, freak. You win hands down this year.
