A condition caused by dropping a hit of LSD and waiting for an hour for the effects of the hallucinogen only to be disappointed that the dose was a total dud, so you take another dose and the first dose starts to kick in twenty minutes later, and then twenty minutes later the second dose begins to take effect, and within the next hour you find yourself in the middle of a parallel universe fucking a carnival ride horse that speaks in tongues; usually this state ends in arrest for multiple felonies and a good lesson learned: LSD results may vary.
1st tripper: I totally got purple unicorned last night?
2nd tripper: How come you're not in jail?
1st tripper: The carnival was closed and I just ended up in a pasture fuckin' a cow.
2nd tripper: How was she?
1st tripper: Fine ... until the bull showed up.

A gesture made to silence a group of people who did not respond to the quiet coyote gesture. The silent unicorn is made by grouping together all fingers to make the nose and mouth of the unicorn and then raising the middle finger for the horn, keeping the top of your hand facing up.
The group did not get quiet after I made it clear I was using the quiet coyote, so I had to pull out the silent unicorn.

A Unicorn Family is a family that is, simply put, too good to be true. All of the family members love and support one another. Internal strife is rare to non-existent. To the outside world they are a perfect family.

A unicorn sighting is something magical that happens or is witnessed, that is otherwise indescribable. Usually it is a so-bad-that-it's-good type of situation or circumstance that is witnessed.
"Hey, I just saw a clown walk up to a bar and try to order a 5 dollar drink with pennies, and it's 2 in the afternoon. That's like, I don't even know."
"I think you just had a unicorn sighting."
