Deadbeat Girl 

Sort of like a deadbeat father. This girl has nothing to offer and cannot do anything at all for a guy. She probably sponges off of him and gives nothing in return. Basically This girl cannot better any mans life and is a waste of time. More times than not, she is a crazy, party girl.

Hey Jay. What happened with you and your girlfriend?

She turned out to be a deadbeat girl, so we broke up.
