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. By no means derogatory but quite the opposite, a rare treat.

A Unicorn can refer to a man or a woman and is often used to describe the perfect catch or perfect partner. A Unicorn is a mythical creature, someone amazing who is hard to catch or simply a very rare find. The term is often describing someone who is remarkably attractive (above a 7.9), but not at all batshit crazy, amazing at sex, and has a great personality. This definition is used more often to describe this scenario than in reference to LGBT themes. Gay or straight however you can be a Unicorn because you're beautiful, amazing, fuck like a god/goddess, not crazy as fuck, awesome to be around and even going somewhere with your life. Hot but down to earth? You may be a Unicorn. People will try to catch the Unicorn as if hoping to bring this magical energy in their life but the Unicorn knows only to reveal themselves to the worthy. This makes the encounter all the more magical because it's not a trick of the light it's a mystical mythical magical babe that makes you feel so lucky because you never thought you could find someone amazing as them. Careful, these folks can make the hard of heart easily fall in love.

That girl that you can't catch. Everything about her is so perfect (divine, if you will) getting with her is unfathomable. She is truly a blessing from God. Bumping into her on the sidewalk is a good day. Holding a conversation with her... you were probably dreaming. Anything beyond that - good luck. It takes time, effort, and a whole lot of persistency. But never give up; unicorns are said to be "uncatchable," but nothing is impossible. Impossible is nothing. Under no circumstances, never ever, not ever, at no time, should you ever marry a girl who is not your unicorn... Unless you have some super square wheels, then you should look up the word "Swamp Donkey." Everyone has a unicorn; it's just a matter of spotting her and tracking her down. Give it time, it will happen. "For destiny grants us our wishes, but in its own way, in order to give us something beyond our wishes." Good will hunting boiiis.
"Dude, did you just see that broad? I think I just found my unicorn. Now how do I go about talking to her?"

“That girl is a ten for sure.” “No bro, she’s not a ten - she’s beyond a ten. She’s my unicorn.”

Amy: "I've been on seventy four dates in three months and I haven't met any quality guys yet!"
Bob: "Guys? Sounds like you're trying to date a unicorn!"

Colloquial; Synonym for hot bi babe or HBB, often derogatory, condescending, or ironic. A bisexual person, usually though not always female, who is willing to join an existing couple, often with the presumption that this person will date and become sexually involved with both members of that couple, and not demand anything or do anything which might cause problems or inconvenience to that couple.

The term is often used to be dismissive of a couple seen to be only superficially polyamorous. Because of the demands that this type of couple places on the woman (that she be single and not take on any additional partners, and become involved with both members of the couple equally, and often "complete" their family as a surrogate mother and housekeeper and/or breadwinner and not do anything that may threaten or disrupt the existing couple), many in the poly community call this type of woman a "unicorn", as in mythical and not likely to be found, even though there are plenty of bipoly women around.

Sometimes the unicorn is expected to not develop any emotional attachment and is strictly there for a sexual relationship (equally distributed to both members of the dyad) and/or is prescripted as a secondary. This term is used as a reminder that bipoly women are people with their own desires, needs, and pre-existing lives, and not fantasy figures or pets. See related prescriptive vs. descriptive.
John wants a single, attractive woman who will love and have sex equally with him and his wife, but not interfere with their marriage, move in together, help raise their kids but not have any of her own, and not have any other partners. He's looking for something that doesn't exist - he's looking for a unicorn!

A mythical species of horse that is extremely hard,if not impossible to catch. Only virgins can come near a unicorn.A unicorn's horn is known to neutralize poison, cure any disease, resurrect the dead, and the unicorn itself will choose its companion. If you ever meet a unicorn, if it is not looking at you, or coming near you, forget about being its companion, or even coming near it. If you manage to capture the unicorn, you will obtain immortality. Don't cage in a unicorn when you keep it. It will run away.
Ian went into the forest for a week, trying to find a unicorn. But, he wasn't a virgin, so he wasted his time.
