Some people just genuinely think they are above others for whatever reason they decide to use in order to feel that way.

Some people enjoy their spot on a social ladder, and if someone they have perceived on a lower rung begins socializing at their level they close them out. That is about the best I can do to define "stuck up". They do it, I think, because if the rungs below them disintegrate, then they are no longer "better". It is a sickness they enjoy because it feeds their ego. And they HAVE to exist in groups, not individuals, because that is the whole point of the game, "SOCIAL ladder". It happens in middle school, high school, and college. So what, then we all just want to pretend that it doesn't exist as adults? Come on.

So I ask you, do people like this exist?
