A game called "naughty numbers" in which you spread a deck of cards on the floor, (remove the kings and queens.) Flip all the cards face down. Now, someone picks up a card, and someone else has to dare them to do something the number of times inidicated on the card chosen. (Usually sexual.)
Examples of dares in naughty numbers:
1. Mosh whilst naked # times!
2. Flash people # times.
3. Shed # peices of clothing.
4. Etc. :)
