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!

Rainbowfairy fart dust

A belief someone has in something that is untrue and nonsense bullshit.

This chick is living in fantasy land after all the rainbowfairy fart dust she heard from the psychic the other night.

Fart Dust

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.
