What does "Prep School Riot" mean on the back of a Juicy Cuture Jacket mean?

I was shopping at Nordstrom's and I got a Juicy Couture Valore Sweat outfit. When I brought it home, I realized it had "prep school riot" on the back. Any ideas on what that means?

preps are retarded and they would get destroyed in a riot so probably something stupid im sure
