sex-lationship

a relationship that revolves completely around sex, so much so that the people are not even considered to be "in a relationship" but simply just hooking up. it is different from a one night stand in that it lasts longer than one night and at least one person feels an emotional bond that most likely isn't even there.

Girl #1: Joe and Kate really need to stop their sex-lationship and either start dating or stop fucking.
Girl #2: Seriously.
