Psychology Today: The Polyamorists Next Door
By Elisabeth A. Sheff
Another home-made polyamorous word, metamour is the term for a partner’s partner. Your girlfriend’s sweetie or husband’s boyfriend is a metamour. As friends or chosen family members, metamours are linked through a polyamorous relationship but are not in a romantic relationship with each other. Rather, they are members of the same polycule (a family/small network of people united around a shared polyamorous relationship, not all of whom are lovers but share lovers in common) and hang out together to various degrees.
