Reverse cropdust 

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.

Reverse Cropdust 

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"

Reverse Cropdust 

When you fart and then call someone over to you.

I farted and asked my friend John to come look at a meme on my phone, sharing the lovely flowery smell of almost shitting my pants, reverse cropdusting him.

Reverse crop dust 

When a person farts and that said person uses a fan of any kind to blow the stench in the victims’ path.

“Dude! Rick got me with a gnarly reverse crop dust with his box fan, it was terrible!”
