In my fanfic, I have the same cliques as the ones in Bully with the following included:
- Emos
- Goths
- Skaters
And then local cliques who don't attend college:
- Bald Rocks, a near full-fledged skinhead metal gang
- Pink Serpents (blue collar punks, similar to the townies, but pink is their color instead of orange)
- Underworld Medusas MC, a biker gang
- Apaches, whom are mostly rehab'ed criminals now attending a military academy
