FWBs 

abbreviation for friends with benefits.

acting with a friend as if you were in a relationship, but causing no conflict.
basically, regular friends, but a little more extra action.

Chick1: "Being FWBs is getting annoying."
Chick2: "Yeah, why can't that boy just ask you to be his girlfriend?"
