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')

Multi-slacking

Engaging in many small activities at once, none of which are productive. Usually, but not always, involving a computer and its applications (iTunes, AIM, YouTube, etc.), can also include watching a movie or TV show, listening to the radio, talking or texting on the phone, or any other ultimately trivial, meaningless activity.

That dude was multi-slacking like mad when he should have been working.
