You know, after reading those comments, I'm wondering... are Juggalos just Phish fans, but with slightly worse taste in music?
I mean, the lingo is different, sure. They're violent, and uniformly lower class. But they've got the same "Just be cool and accept me for who I am!" vibe, and they seem to like huge bacchanalian get-togethers.
I may have to do further research. God help me.
