A new relationship status called an "ish," falls between a friend with benefits and a boyfriend/girlfriend. When you are in an "ish," you have the pros of the friend with benefits as well as those of a boyfriend/girlfriend status because you receive the sexual attention you want as well as having someone care for you platonically. A noteworthy difference between a true relationship and an "ish" is that in an "ish," there is no exclusivity. In a relationship exclusivity is assumed, while in an "ish" it is up for discussion.
1) We're not going out, but it's more than just hooking up; I'd say we're an ish.
2) Sean: "so me and Cait broke up"
Nishant: "The fuck are you talking about. You weren't together"
Shelley: "They were just ishes"
