Dropping continuous farts while walking through shopping aisles or large crowds, leaving the smell for everyone else to enjoy while you casually walk on.
"Careful, don't go up the stairs, I was crop dusting all the way down!"

The act of walking past somebody, and without their knowledge, letting out a fart as you pass. Thus creating the crop dusting effect. Very effective in announcing your presence, or maximizing the devastating effect of your discharge.
*Loud fart*

When you are at a party or a club and you need to fart so you move really quickly somewhere else and fart while you are moving, laying your odor everywhere but where you were.

Usually is really funny.
1 Hey man, I gotta fart, really badly.
2 Don't do it here, go crop dusting.
1 O shit, thats right.

Surreptitiously farting while passing thru a CUBE FARM,
then enjoying the sounds of dismay and disgust; leading to PRAIRIE DOGGING while people try to figure out the source of the wafting stench.
Bob liked all the prairie dogging his crop dusting produced.

When a man makes a woman lay on her stomach, letting her think she is getting the rod from behind. While she isn't looking the man sticks out his tongue and, like a crop dusting airplane, hovers over the girls ass until deciding to dip low and lick the girls butt hole. This may be a continual vigorous motion or the man may choose to fly by making many periodic passes. This method of Crop Dusting is not to be confused with the fart procedure of crop dusting.
Jamario made jo-nelle lay on her stomach while he moved his head around her ass licking the butt hole periodically. Thus he went sexually crop dusting with jo-nelle.
