I think you left out nerds

Another group exists which, although present in every American school, has never been adequately named. They tend to be highly intelligent, often more so than the preps or nerds, wear six pocket cargo pants with a solid color t-shirt underneath an unbuttoned plaid shirt (usually some form of blue) and listen to late sixties-mid eighies classic rock.

and what about jocks? those who butt heads and make mother gags incessantly? there's a wealth of material to be mined here..

that group (of the smart ones with the cargos) is so true. Its a large part of many american high schools. but often, those people fit into the prep group too.

There is another group, too, the Drama group. They are the ones who will go to extremes for attention. They tend to be rather intelligent but not always, and come in a variety of personalities. They are generally very accepting, provided you have some acting skill or are willing to help out backstage during a production. They love nothing more than a good laugh, and are among the more creative people on campus. Usually nice people, they do tend to hold grudges for quite a while, although they don't do much about it.
