Anal Dust

The dried semen particles that explode out of the anus during flatulence shortly after intercourse.

I was walking behind Shannon when I got a face full of Anal Dust. We all know what she did last night.

Anal Dust

The scrapings of your shit and fart residue on your underwear, and the act of taking a dab of it.

I was so fucked up from that anal dust earlier.
