Shacking Up

Regularly hitting the sheets with someone youare not dating OR casually moving in with someone you regularly hit the sheets with.

Living in sin.

Shacking

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.

You have no preparation....no toothbrush or extra clothes. You have to wear what you wore out the night before. You should also add that you usually get dropped off in a random parking lot where you left your car, if you can remember where it is. (see term 'walk of shame')
