Saw this discussion in the PS3 subforum for PSN names so I thought I'd start one here.

A few I've seen:

DONT SHOOOOOOOT

FOLLOWMEIAMNOOB (he wasn't a noob)

WWWMMMWWMWWMMW (or something like that - causes some games to glitch because it's so long)

Forty People (so it shows up "You Killed Forty People")

Yorselph (as in Yourself)

Any you've seen?

EDIT: Names like L3g1Tz Sn1PeZz are unoriginal and lame.
