Pronounced "TRAY-STER"

That one guy that everyone makes fun in class because he thinks he knows everything, and thus has an answer to any question.

...before anyone else has a chance to think...

Professor: Woah! Hold on for a minute! I think you have things mixed up!

Me: Yeah, you fuckin' TROESTER, shut the hell up!
