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.

The rare creature who is able to give you the thing you always wanted but thought you you could never have.
"You fell in love with a unicorn. It was beautiful, then sad, then sadder. I laughed, I cried, I puked in my mouth a little. And honestly, I kind of get it."

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.
