Here's a theory that my drunken roomates and I came up with.
The reason that most good looking girls are b10tches stems from childhood. You see, the good looking girls you see today were probably good looking teenagers, that is, they were good looking in their formative years. Whenever faced with a social situation they were treated nicely because they were good looking, and therefore didn't really need to do anything to get what they wanted or receive nice treatment. Therefore, they get this idea in their mind that since they're good looking, they have the right to be bi0tches because they can get what they want anyways. This explains why a lot of "hot" sorority girls (and meathead jocks) are void of personality.
People often overlook the meek looking girls, but they are probably the funniest/nicest and have the best personalities, since, in theory they didn't have the "crutch" of "stunning looks" to get them through their teenage years, they had to rely on their personalities (shocking).
You can't judge people by how they look sometimes. My roommates and I concluded our theory with the conception of the perfect girl. There are 2 paths.
1. Girls who don't know they're pretty.
2. Girls who weren't very pretty as a teenager, and as in the 2nd paragraph of this post, relied on their personality and therefore developed a good personality but then later somehow got hot.
Oh #2. Where are you?
