Used in polyamorous contexts, a person's lover's other lover. A partner's partner, the person your sweetie is banging, etc. Unlike mistress or paramour, "metamore" connotes that neither relationship is clandestine.
There was a lot of tension in my relationship with Joe, so I had dinner and talked through it with a metamour, Casey. They were able to bring a lot of perspective, and things with Joe really smoothed out. The next week we made an Eiffel Tower.

Now that I'm dating Ludacris, I have metamours in every area code.
