Personally, I hang out with people I find interesting and intelligent. I despise stereotypical cookie-cutters who "buy the right clothes", get the same interests as everyone else and things like that. Honestly, when it comes to dating, the only property I really don't want to encounter is predictability. Stupid people are generally extremely predictable most of the time. Besides, anyone using the term "dumb blonde" should be shot repeatedly in the groin.
