wow! our high school had nothing of that sort. I really dont think it sounds like anything i would want to be a part of anyway considering you said you had to spend one night in torture. To be honest with you, nothing is worth it if you have to go through that, and what for? just to say you are a part of it? Dont think so! Glad no one from my high school participated in anything like that.
Thanks for letting me know what it was!
