basement boy 

A failson or slacker who lives in his mother's basement or off the support of his mother. An offshoot of a momma's boy, he fancies himself to be self-reliant and drastically overestimates his competence in life.

Never date a basement boy. He'll mooch off of you and constantly ask you to make him sandwiches.
