Actually Arrow X doesn't do that, since he even pretty much accepts the fact that he's the forum bitch who gets his ass kicked by everyone all the time. (Except sports)
kellychaos doesn't really qualify either, he just types stupid shit and piles it on. (Much like Matt and Esuohlim)
I'd say Mike and Fartin have more of the "I always win mentality"
So this is the following order:
Mad Max
Lotida
Fartinmowler
Mike
mubert doesn't count because he was a character I created.
