prep

A person who is completely and utterly EVIL. Usually wealthier than the average peon, and just plain old annoying and mean. They are usually considered the "popular" group and everyone hates them because they're always fake. They talk about everybody, even their own friends. Most likely, preps are the ones making fun of the "scenes", "emos", "indies", "hipsters", and everyone who's NOT a prep.

I've never met a "good" prep in my entire life.

Girl 1: Oh, she's a popular girl, isn't she?

Girl 2: Yeah. She's a prep. She runs the school, makes fun of everybody, and will make this school a living hell. We try to stay away from her.

Girl 1: Does she know that people hate her so much?

Girl 2: Probably not, everyone here's fake and pretend to be her friend.
