First off the laugh and how stupid it is. Incredibly obnoxious, and its so asinine how holding the hand in front of the mouth is.

They're also a type of spoiled brat/elitist character, which always goes one of two ways. One, you see that they're insecure and are actually a good and decent person, but they're just so caught up with appearances and not wanting people to get close to them. So they self-sabotage. They intentionally isolate themselves at the top of the social strata and don't let others up there. It's not because they hate people, it's because they hate themselves and don't want to interrogate it when people actually want to be friends. It's simpler and easier to just be aloof and alone. Believe it or not, I find that really relatable.

The second is that they actually ARE a piece of shit, and 100% of the time they end up being humbled in the funniest/most extreme way.
