A theoretical person of either gender in any context whose qualities are so idealized that it precludes their existence. Someone who is literally too good to be true.

A single bisexual female who has intimate relations with couples in the swinger community. Some unicorns are only around for hot one night stands. Some unicorns form long term relationships with the couple(s) they become involved with. This kind of woman is indeed rare, so rare some say they've never met one.
We're really hoping to finally catch a unicorn at the swinger's club tonight.

We keep a unicorn around to spice up our marriage.

Hey babe, want to see if our unicorn wants to join in this Friday?

Unicorns are kept In hair dye factories to make exotic colors such as vivid or non purples, blues, and pinks. The hair dye is used from the unicorns blood... if you have ever wandered why you never see unicorns or people think they don't exist, there is only one possible reason the hair dye companies keep them held hostage in their factories to make unlimited supplies of hair dye.
Unicorns are magical creatures that nobody believed existed until now.😊 thanks to me.

Unicorns are a creature supposed to be mythical. The ones in myths are typically breathtakingly beautiful, and their horns are known to have magical properties. Unicorn blood will keep a person alive, or immortal even. While this type is not real, there is a unicorn that is. It is actually rather ugly, with no magical powers, but it is the national animal of Scotland. Look this up; you’ll see it’s true.

Other small fact: Marco Polo thought rhinos were unicorns!

It's when you lay down flat on you back, face up, with a dildo suctioned to your forehead, and your partner squats down over your head, and inserts the dildo into one of their orafaces, then bounces up and down over you while singing The Irish Rovers, The Unicorn Song.
