Inbreds
low intelligence, attempts to compensate by studying extra hard resulting in hilarious amounts of ego inflation, making them extra vulnerable to mass butthurt. most have no social life other than WoW and studying. are extra vulnerable to mass butthurt.
Tryhards
similar to inbreds, only they're less socially awkward and instead of studying, they usually take up a sport or instrument, they get Unwarrented Self Respect syndrome for being the perfect tool. also prone to butthurt.
The Rich Kids
the scum of the school, they're ungrateful for what they have and put no extra effort forth despite having more resources than everyone else, instead they'll be daddy little angel and buy the latest technocrap.
The Lazyasses
Don't care about anything, don't get involved in anything "serious", and give no forgets about anyone's problems. they just do whats necessary to get a diploma. strangely enough a rare specimen.
The Edgy Kids
Worse than the inbreds, they do whatever is "in" and usually can be spotted wearing fedoras. unlike tryhards or inbreds, they use any advantage they have such as height or "status" to acheive a fatal amount of USI. common targets for "trolling".
there's more but the list would just be a wall of text.
