How'd you decide on your nickname(on the forums)

I use many nicks on the internet, I chose my universal nick: Gannon133. That nick I chose was because when I used to play Super Smash Bros. Melee, I used Ganondorf, which wasn't actually chosen for the matches and the guys that I played with lost about 133 times in a row whenever I chose him, and I haven't died when using that character. I actually use the bad naming of Ganon because that explains the gaming situation I am playing: a loose Ganon.
