person 1: ..and they were roommates!
person 2: Oh my god they were roommates.
Two men sharing a room and woman.
e.g. Eskimo Brothers
Those two guys moved in with this chick and became Canadian Roommates
Co-parents/Non married couple with a baby living together
Susie and John Dick were roommates and they had a baby together and now she’s a babymama roommate
The risky act of opening your room/residence without knocking and hoping to not find your roommate in the middle of a sexual act
Sam: *thinking* ‘my roommate stepped out I should be good for a quicky’
Darrel: *opens room door without knocking* brother eeewwhhh!!!!!!!! You have caused me to lose roommate roulette
Males only. There's really no way to win, but you lose when you see your roommate's dick.
"Yeah, he made me lose the roommate game."
