Fart Dust

A really dry flatulence which upon exiting the anus emits dust which then can be seen on the inner lining of the undergarment as a powder like substance which falls away upon removal of said undergarment.

Hey Bill, check out my collection of fart dust I have here in this jar. It weighs almost 10 pounds!

When you have to shit, but only a fart come's spraying out yo bootyhole.

I just had to run to the bathroom, only to fucking fart dust.

Unicorn Fart Dust

dismissive term to describe something valueless or insignificant

My boss dismissed my idea as unicorn fart dust, but six months later our competitor launched the exact same thing and made millions.
