I live in small town so it's not very diverse but,
Druggies Obviously obvious, do drugs, pretend not to, they seem like just plain handicaps before you figure out their interests
Jocks Its actually backwards at my school, being rich or anyone even knowing your family is middle class spits you out of the group instantly, play sports, they get along with nerds, especially the girls, I'm not really sure why. and also, if your black, you're automatically put into this group, not because you're poor, but just because you're black
Nerds Make it painfully obvious they're antisocial towards anyone, even other nerds, they're liked by the jocks, and more or less disliked by everyone else
Rednecks Hunting, fishing, basically anything that involves hurting animals and/or other humans
Bad Group Wears all black, have piercings, carry around pocket knives, they're pretty ok in class, but become starfishs outside of it
handicaps Everyone with a special needs, need a helper that ends up bugging everyone else in the process of helping the special kid, generally disliked, everyone stays away from em
Outcasts Where in the other group before, but that group either pushed em out, or it just dismantled and they left the remaining to fend for themeselves. Me and my friends fit into this group. Some nerds, some left over jocks, probably one from each other group. Also added they're entirely anti-social to anyone except anyone in their immediate friend group, meaning they generally only talk to a few undergroundr's
Underground They don't have any special group to fit into, they'll sometimes have friends in one or more other group, but some are just loud and try to be friends with everyone, which usually fails horribly and makes them look dumb
Outcasts 2.0 Almost the same as the outcasts, but with alot more girls, and alot more handicaps, also generally don't even talk to anyone, even the underground
probably missing a few but whatever
