Oh, I've been DYING to respond to a topic like this. I have a hate for the popular kids. VERY big hate. They are shallow to everybody at our school and act like they rule the place. There are about 3 exceptions, and them I actually get along well with.
It isn't some stereotypical hate-I'm actually very well-liked at my school. But oh my, the popular kids need to get over themselves. I've heard people talk about me (yet they're too absentminded to realise I'm listening X_x) and think they're all funny, and I just sigh. I don't care what they say since it's just their own egos being inflated that much more.
They think talking about inappropraite things is all hilarious...and I mean REALLY bad stuff. One of them was craving attention so much that he wrote a bunch of..."bad" terms on the chalkboard and started singing them to the class when the teacher was out of the room :0
And today at pictures, they all thought it would be funny-for the school picture-to stick their tongues out and think they're all funny.
Though now that I think about it, I wish I would have voted 50/50 since many don't fit the description I just gave. the ones that do anger me to no end (though they're starting to figure out that there are going to be consequences for their doings). I mean, the ones that do fit my description really are /THAT/ bad, but the others (about 30%-50%) are really nice and fun to talk to. So meh, they're not all too bad. But again, many are, and it is getting increasingly "lol" that they think they're so great at everything.
EDIT: Again, this is only from personal experience. It's just that our pop. kids are really mean to other students and that's what I'm basing this on...I tried to keep in unbiased, probably failed T_T
