When your man puts powdered sugar on his man meat and you have anal and when he is finished you fart brown powdered sugar into his face. Thus the 'dust' bombing.

Get the Dust bombing mug.a nasty ass bowel movement that covers everything in feces and poop dust, much like an ass explosion of diarrhea or a bad case of swamp ass. seriously entertaining !!!
The bathroom at work smelled like boiled dinner, I knew immediately who had dropped the poop dust bomb in there !!!
