I went with a group of 8 people, we then met up with girls, t'was fun.
Also @ op, find them, report them. Or if you want to piss the stuff out of them, do cruel stuff like egging, teepee'ing, ding dong ditching, well that's not cruel. But when you do get them pissed and after you, get a bunch of friends and corner them, and threaten them/beat the stuff out of them, that's cruel but payback is a bitch, right?
Don't let people forget with you.
