Don't you just feel like killing these people?

Like the kids in High School/College who think they're all that. They think they're the smartest in the cl and rule the school. They'll always be sucking up to the teacher to get A's and whine if they get anything lower they'll correct you for any mistakes you make (which is really annoying) but if you correct them with any slight mistake they'll start bitching and hate your guts lol. They think they're so cool with every new iphone they have, use internet acronyms offline (eg. W.T.F.) ***** at you for breaking the slightest rule and go tell on you, have greasy hair but they know about it they just don't care, shush you out rudely if you try joining their conversations and talk about weird crap? Don't you just feel like slapping them upside the face?
