Skateboarding, music, Art, especially forms of street art, and cartooning.
Anyone that ever incited a serious riot.
This gets hard to update nowadays. Just know Punk, surf, (real) Hardcore, Grind, Power violence, Any fast form of metal, jazz, folk, and a good amount of hip hop.
Fight Club, Pulp Fiction, Reservoir Dogs, Bomb the System, 40 Year Old Virgin, Dumb and Dumber, Kids, Bully, The Filth and the Fury, Clerks, Mallrats, Dogma. I watch too many skate videos to get into a lot of movies.
South Park, Drawn Together, The Fairly Oddparents, The entire Adult Swim comedy set(Squidbillies, ATHF, Robot Chiken, etc). just lots of cartoons and stand-up comedy I guess.
Not Jonathan Safran Foer. That's all that needs to be said on this one.
