Anti-Prep is a person that stnads up for their own means. They don't have to take any shit from the jocks, gear heads or anyone for that matter. They are considered a rebel for everything that they do and everything that they can come up with in their own little world. No on can understand them. Not even if they tried or wanted to. Not many people want to be like them for that fact.
Most outcasts are anti-prep and should be!
