Freeloading

[Merna]

A person who is a freeloading is a person who is basically using you -- most often for a place to live/room and board: a place to stay permanetly if they can or just to crash if necessary; a free meal ticket; drugs; clothing; transportation; entertainment, and money-- basically whatever they can get their greedy lil paws on.

Freeloading requires one to be extrememly manipulative and kniving.
