A man who is called upon for simple maintenance issues a woman may have. For example, unclogging her pipes, knocking wood, or laying pipe. The woman is typically a YUPI who is not interested in a relationship, at least not with the man in question. The maintenance man usually does his job in the late evening and leaves when the "job" is complete. Maintenance man services are free of charge.
Ex. 1: I hear Baltimore has a lot of girls just looking for a maintenance man.
Ex. 2: Yeh, I'm doing part time maintenance man work now, but I'm looking to pick up a few more clients.
