An acquaintance that you, yet not your friends, desire although you know little to nothing about him/her. The mythical and enigmatic reference pertains to your unfamiliarity with your person of desire and the reason for the attraction in the first place.
"I heard you went home with your unicorn last night!...yeah?"

As rare a real unicorn is. This fascinating sexual experience is when a female giving you fellatio starts to migrate south to your butthole. As she tosses your salad she begins to jerk your member. At this specific moment, she resembles a unicorn polishing her horn (your penis). Yes, it is as magnificent, rare, and pleasurable as it sounds. I would recommend that if any of my fellow alpha males find a women that expresses her love of the unicorn that you wife her IMMEDIATELY. Enjoy!
While the fugazi started to give me head, she went down, started eating my ass and jerking me off and the same damn time. I unicorned that bitch bro! Female: Hey baby! Make me into a unicorn!

An intellectual female who is considered pretty, sexy, hot, or any similar thing.
I knew she was hot, but I didn't know she was a unicorn! Score!

The upper class of the equestrian world. Because of their magical powers and sociopathic tendencies, they are typically land owners, government officials, and general rich, pompous douche bags. They often look down on and exploit the other species- most especially the ponies. Because of their arrogant, self centered nature, and frequent impotence on the part of the male, they have a high divorce rate and combined with the likelihood of being hunted down by goblins for their magical horn, consequently low population- much to the relief of the other species.
That unicorn paid the police to evict all the ponies from their land. I hope he's hunted down by goblins.

A unicorn is an individual that has all of the ideals and qualities that you are looking for in another human. Like the mystical horned creature, you may never see one of these in person, only in dreams.
I met this guy I thought was a unicorn but turns out he is ___ (insert appropriate word).
