Notorious in college but high school can have major ones as well. Its not just a party but a massive party that usually consists of crazy shit happening. Keggers are a must. The party is so full that you can barely move around.

A term used in the midwest to describe someone who is basically both a hippie and a raver, almost always a dealer of extremely hard to find psychedelics, wears a wrap, loves dubstep and bassnectar and also goes to schwagstock and carbondale alot, and is more than likely a member of the grateful dead family, but also hits up the warehouse party, but only when there's a suitable amount of dubstep. This person can get you the absolute best molly and shrooms in the world, but don't trust the "mescaline" or "rc's", and definitely don't trust the L or deemster unless you know for a fact that this person is down with the super heady business.
Person 1: Don't trust those ragers over there.
Person 2: What kind of god thought hippie-raver hybrid was a good idea anyway?
Person 3: Dude, that rager just hooked me up with some 4-Aco-Mipt. Wicked!
