ICP 

A rap duo from detroit consisting of two of the smartest caucasians I have ever seen in my entire life. What they do is make a few off-tempo beats that could easily be bettered on a child's toy keyboard, and scream and talk about random shit they think about when they get high on peyote about clowns, then they'll put it on a cd, slap on a couple ugly pictures of themselves in retarded clown garb, and make millions from retarded white emo kids who don't know any better. They get rich off of being worthless.

Juggalo: OHHHH YEAH, This is the new shit from ICP!!!!
Normal Human Being: He wasn't kidding when he called it shit.
...Why do juggalos like faygo?
Because it's pure shit, just like their music.
