Good Cheap Group Costumes???

[T.G]

Don't dress up. Maybe a few of you get some temporary tattoos or something, but that's it.

Then spend the entire night yelling, arguing, throwing sh!t at each other, crying, hugging and making up. Every now and then all huddle together and start whispering about the one person who didn't make it into the huddle. Then call for a "vote" and ostracize that person from the party.

When someone asks what you guys are there as, tell them "reality show contestants" and then challenge them to a fight.
