Unicorn
A single, often bisexual, person who joins an existing couple for play — rare and to be approached respectfully.
In libertine and swinging communities, a unicorn is a single person — most often a bisexual woman — who joins an existing couple. The term reflects the rarity of finding someone whose desires align cleanly with a couple's. Modern etiquette stresses treating unicorns as full participants, not accessories.
