In a polyamorous relationship, where your lover has more than one lover, a metamour is the name given to your partner's other lover(s).

3.
Your partner's other partners, that you are not romantically or sexually involved with. My girl/boyfriend's other boy/girlfriends.

A partner has several other partners. Each partner of a partner is a metamour. Collectively they are all metamours. Often used in polyamorous communities.
I'm dating F. He also has a partner J and another partner Z. J and Z are my metamours. We practice polyamory.
