mon_of_steele,
Lay low and be quiet about it. Learn everything you can about them. They'll be hanging around in 2 weeks like nothign happened, so you identify then when you see them. Hide. Follow them home. Get their addresses.
Post their addresses here. We'll get their parents' names, job location, etc. Snap a few cell phone pics of the kdis too. Then set us loose on it. Imagine how mortificied their parents will be when photochops of their a-hole kids start arriving in their co-workers E-mailboxes.
Getbig is all about justice. You have been done a great injustice. You just snap some pics and get their addresses, and let the wonderful people here help you repay them. When little johnny comes home from egging to an ass-whooping from a mortified dad, you'll have your payback. Heck, that's just one idea... I'm sure there are many more.
