My high school had these cliques:

The Stratford Geeks (the Geeks who took all the IB courses and were always on the Stratford campus - my highschool was so large, it had two campuses.)
The Stratford Jocks (A select few who chose to stay on the acadamic campus)
The Stratford Russians (An ethnic group that wasnot limited to being geeks and jocks, but had their own little niche.)
The Grade 9'ers (Stratford campus had a grade 9 class.)
The 3rd Floor Geeks (computer geeks who spent their lunches on the 3rd floor labs a lot.)
The 6th Floor Geeks (Music and art nerds hung up there.)
The Preps (the ones who tried looking homogeneous, always hung outside of the tower near the tennis courts.)
The Jocks (school was too big for this group to be a problem.)
The Russian Wing (A whole wing had all the Russian immigrants' lockers.)
The Chinese Wing (A whole wing had all the Chinese immigrants' lockers.)
The Hall Geeks (Hung up on the East portion of the 2nd floor main ring. These guys took the AP courses.)
The Stoners (Hung out in the Industrial Wings.)
The Stratford Hoppers (these were the unfortunate ones who had to hop on the shuttle busses between campuses between each class.)
