fam burgler 

Someone who's known for stealing from, or fuckin' over their friends or family. Fam burglers usually steal things that are easy to conceal and carry in a coat or pants pocket, a purse or backpack and most likely won't obviously be missed right away.

ROOMMATE: Hey, you seen my phone?

ME: Chris was here at the party last night wadn't he? I bet he took it when he left this morning while you was passed out. I tried to tell you don't let him up in here. That muhfucka's a fam burgler, for real.
