Greydigger 

Someone who gets into relationships mainly in order to exploit their partner’s willingness to labor, for instance by having said partner do chores the digger finds tedious.

“My girlfriend is awesome. I do all her homework for her and then we make out.”
“Bro you sure she ain’t a greydigger?”
“The fuck is that?”
“See above.”
