What is Aim Oldbie?
Term generously applied to oneself to make oneself feel better, and to mask the fact that one's head is so far up one's ass that they can't apply nor comprehend common logic; i.e., someone who ruins online roleplay by criticizing it, when the term "oldbie" originated on AIM via roleplay. Nearly always self applied status, as practically no one would call another an oldbie unless asked.
"ROFL HAHA LOL I'm an oldbie you stupid n00b."
Translation: I have no life and am making an outcry by calling myself an oldbie, and trying to insult you.
