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.

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.

When one walks up and down the aisles of a store while farting periodically.

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.

The art of leaving a long silent but deadly fart while walking through a crowded room or bar covering the whole area.

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.

TO fart as you walk in front of someone in order to make them get the full effect of it.
