quad

A group of four people, or more specifically, two couples, in a polyamorous relationship.

Bob: You and your wife seem awfully friendly with that other couple.
Ted: Yeah, I didn't know how to tell you, but we're a quad.
Bob: What's a quad?
Ted: We're all boyfriends and girlfriends.
Bob: At the same time?
Ted: Sometimes 8-)
