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.
"My wife and I hooked up with a Narwhal last week! It was super hot."
