n00bster
A clueless internet dweeb who thinks they’re cool because they use the word n00bster.
"I’m not a noob, I’m a n00bster!", a kid who got kicked out of a game.
Tweet: "This n00bster can’t even log in properly!", from a tank commander.
DM: "You’re a n00bster, and I’m going to beat you up.", from a Pet Shop Boys fan who’s mad.
