Preps: These are mostly the "popular" girls (or at least they think they are, who are always decked out in the latest fad clothing with big labels across the front and who have a tendency to look down on the rest of the world except for the Jocks, whom they usually hang all over. These are the girls wearing the size 2 shirts that could fit a Barbie doll. There are males of this variety, and they are the kind who typically do everything and anything that is "in", such as styling their hair like a helmet or wearing repulsive hawaiian shirts.
Pure Preps: A rather small subcategory; these girls are fad-hoppers and teeny-boppers, but they are usually (semi) intelligent, religious, and wouldn't be caught dead with any of the boys from the school they go to unless they also are of the intelligent-yet-preppy variety.
Slut Preps (FSA): My pet name for them is "Future Sluts of America". The only thing that keeps them in the "Prep" category is their tendency to wear extremely small brand-name clothing, although it may not fit them, and be snobbish. They look like sluts, they act like sluts, and they will be our next generation of sluts. They are the LOUD girls that wear too much makeup and get in your face for looking at them. Very few males like this, although these girls do usually hang all over the snob jocks.
Jocks: Basically any "macho" acting guy, with or without the jockish muscles. They sometimes keep with the brand-name clothing, fad thing, but more often they are the ones who take any opportunity to flaunt the fact that he is in sports. There are also a few girls like this, but they are less annoying than the males.
Football Jocks: This is just my name for them, but these are the ACTUAL Jocks with the muscles and the ones who have a right to brag.
Snob Jocks: Jocks with an obviously overworked ego.
Nerd Herd: The people who are not considered popular at all but are usually approachable and rather intelligent.
Egg Noodles: The nerds that look like they are made of spaghetti and couldn't do a pull-up if the bar was two inches above their head. The kind you could pick up with two fingers and wobble back and forth.
Class Brain: The kid who can recite the quadratic equation.
Annoying Nerd: Those kids who know everything and love pointing it out
Goths: These people are the ones who dress in dark colors, try to look like zombies, and enjoy being themselves. Not a bad thing at all, they just like expressing themselves through clothing and attitude.
Mopey Goths: The Goths that look how they feel-dark.
Perky Goths: The Goths whose personalities are the opposite of how they look.
Freaks: Those lovely rebelling people who dress and act funky because hey-it's fun!
Nobodys: The people that just float around, doing nothing and not really affecting people that much.
Druggies: The name says it all, although it is possible to be a druggie along with many of the other cliques (jock-druggie, goth-druggie, etc.)
Everybody People:These few people who really can't get anyone mad at them.
The UnClique:: This is the clique for those who lack an actual clique, who talk to people and have friends who may be in one or more clique, but lack any real defining traits.
