Oddly enough, most Juggalos are just hyped up on too much Faygo and adrenaline. They are quite a site to behold though, especially if you are unfamiliar with the sub-culture - it's very testosterone laced, even with the girls (Juggalettes).
Yes, ICP is one of my guilty pleasures (ducks). Although I have to admit I like their label-mates
Twiztid much much more. I take none of it seriously, and all of it very tongue-in-cheek.
I have been to my share of ICP shows, but I never go painted up or get too close to the front of the stage.
You don't know misery until you exit a theater at night in 65 degree weather, soaked to the bone in Diet Root Beer Faygo*, and then have to get into a car and drive home. Never, never, never, never again. (OK, so I did the front-of-the-stage thing once, just to see what it was like. Root Beer and contact lenses are not a good mix.)
ICP (and Twiztid) shows are
very interesting places to people-watch though. I highly recommend bringing lawn chairs and popcorn. Bring small bottles of Faygo too...if they start looking restless, just chuck Faygo towards them and they'll leave you alone.
*ICP sprays the crowd with Faygo during their shows. They use warm Diet Root Beer because it sprays farther and launches the 2-liter bottles farther than any other Faygo flavor.
