Farting while walking through a particular area, then inadvertently walking back through the same area while the fart still lingers.
I completely ruined aisle four with my ass, then remembered I needed a can of black beans and totally reverse cropdusted myself.

The act of surreptitiously releasing farts into a high traffic area like a hallway so that the gas is whisked along with the unsuspecting pedestrian carriers. A role reversal of crop dusting achieving the same effect.
"Bro did you see the looks on those army joes walking by? I've been reverse cropdusting large groups that stroll past. They keep blaming randoms. I'm dying here"
