Hey!
One fraternity on campus throws one every semester for a rush event..
its TONS of fun..
we don't have houses here but they get permission to do it on campus at one of the buildings...there is like a lowered pit outside that they corral off and stuff.. ive gone 2wice already and both times were a lot of fun.. the foam hurts when it gets in the eyes.. but other than that its definitly fun..
