These kids, the weird art kids, don't really fit in with any particular group, so they all sit together, united by their shared passion for really specific niches of pop culture. Some of them are incredibly talented, but the rest of the school would never know it because they devote all of those talents to weird stuff like erotic fan art of minor fictional characters.

They generally keep to themselves when talking to people outside of their group, but have no problem loudly expressing their opinions when they all get together.
