No! That's not what it is.. get your mind out of the gutter, you pervert! Bush diving is a sport best left to the complete insane varsity students who invariably end up doing it as a stunt or for a cheap thrill. At its safest, it involves wearing as much of your old clothes as you can, maybe a helmet if you have one, driving out into the woods, and jumping down a steep incline that's saturated with thick bushes. Usually you'll come out of it with minor scratches and abrasions and a ton of bruises, but I've heard of guys doing it with just shorts and t-shirts and catching thorn bushes along the way. a) that can't be fun and b) I hope you have medical aid or at least a good funeral plan. Yet another in a long line of dumbass macho things for a man to do when he's young.
