The Jocks and the popular kids (A.K.A. DOUCHE BAGS) are at the top, and they go around annoying the shit out of people. They create failjokes that end up bieng wierd and people laugh because it is stupid.
DOUCHES DERP HARD
The middle class is the Average Kids. They at least have some intellegence yet they are basically an "everyman" and want to blend in.
The bottom class is full of nerds/geeks. To clear up the confusion between nerds and geeks, a nerd is smart and gets perfect - nearly perfect scores on everything. Most play video games. Geeks are like nerds except the fact that they lack intellegence although they are skilled in video games.
