What stereotype pisses you off the most?

We all know the kids. The wangsters, the fake hicks, the gym bro's, but if you could get rid of one group of stereotypical people, what group would it be? keep in mind this ISN'T a blanket statements, not all snowboarders are the douchy park bro's, not all rednecks get their inspiration from a shitty reality show, and not a juggalos are worthless. Well, Idk about that last one. But you get the idea.
