Someone who's the BIGGEST n00b on an MMORPG like Sherwood Dungeon, the biggest festering of little, annoying n00bs on the planet.
(if it's not in "" he/she's not saying it.)
player a: DDDDIIIIIEEEEE!
player b: "fk off, n00bimus prime. i'm a part of the audience, not a ring fighter."
you then run back and forth just to dodge their attacks.
player a: uh? burret dur... durdeh dur... huh??
if they won't piss off for a while, you fuck them up!
player b is waving fist and headbanging to Rammstein.
player b: "THAT'S RIGHT, n00bIMUS PRIME!! YOU SUCK!!"
