a term used when a member of one sex spontaneously spends the night with a member of the opposite sex in a non-platonic way, usually following a night of bar-going or after a fabulous date.

The act of staying at someone else's house overnight, in order to make a person jealous. You don't necessarily have to do anything sexual, just as long as the other person thinks you did.

Lying on some type of furniture, preferably of a futon nature. Usually two females, or one male and one female. Involving talking, bonding, and much fun but on an entirely platonic level. Powwowing is an exceptable activity while shacking.
