The stereotypes that come with being a gay male, its so annoying when someone is shocked that I like playing sport, hate shopping, have no fashion sense, don't have a high toned voice, am not promiscuous and I don't go to clubs. Honestly some people need to stop watching TV and movies, it's messing with their views on reality.
Edit: Oh and that one time I met a friends uni mate who expressed utter confusion at the fact that I'm gay and play all kinds of FPS's (and dominate at COD). Because the only game I can like is Hello Kitty Island Adventure.
