A Trevian is quite simply someone who goes to New Trier, but lives up to all the stereotypes. Wether it be "vape messiah", drug dealer, imbecile, white chick who blasts bad rap music from her Range Rover while her clique is in the back, etc. Trevians are notoriously rich and obnoxious. I mean really, the movie "Mean Girls" was based on our school. The lesson here is never cross paths with a Trevian.
