Floppy Unicorn: A person wearing a big floppy strap on dildo on their head.
We were at a party at our bosses house, when all of the sudden Rocco came out of the house wearing a strap on dildo. He looked like a Floppy Unicorn 🦄
When you rip off someone's dick and attach it in some form to someone's forehead.
I will cut off your dick and attach it to your head so that way you'd become a floppy dick unicorn you cunt.
