A Unicorn is a common swinging term used in the community to refer to a single female interested in meeting other couples. Described as such due to the rarity of finding said females.

However, a Narwhal is the lesbian version of this. A Narwhal is an unattached female "third" happy to join an existing female couple for extracurricular activities. Narwhals are real, but rare and are the unicorn of the sea.
