2. (negative)
The unreachable love. Too good to be true because her unicorn status is superficial. Because most unicorns are rare and out of touch, the truth of the unicorn is likely askew. Beauty is exaggerated and faults and other unattractive attributes are forgotten or discounted. It’s your true love…Mr. Right… dream girl… and endless pursuit of this unicorn can only lead to disappointment.

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.

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.

A unicorn is somebody who knows they're magical and isn't afraid to show it.
