Well, girls like that are usually just morons who are honestly ugly. Not all girls think that way, but the girls that do think like that usually have to because that's all they have. They don't have brains or brawn, or, really, know how to talk correctly, and they think that they don't need those things. They have to tell themselves that they at least have their looks (when they usually don't) because if they don't have that, what do they have? Nothing.
