look up any word, like lemonparty:
Verb 1. To clean your living space in order to rid it of any evidence that may cause problems when your girlfriend comes over. Pictures of other girls, phone numbers, etc.

2. To throw away all the messy garbage that only a single man would accumulate
My girlfriend came over, but there was no time to debach the apartment.

Look at all these beer cans and cigarette butts. I really need to debach the place.
