Crack House Friend

An intimately close kind of friend, not that you would smoke crack with, but that you could call and say "I'm in a crack house, and I'm scared for my life.", who would then do everything in their power to get you help or help you themselves.

Person 1: Hey, who's your best friend?

Person 2: I don't have best friends, I have Crack House Friends.

Person 1: Dag, yo.
