(v) - When a person has to take a crap so bad that when they pull down their pants to mount their throne, they produce their gassy emmissions all the way down to the toilet seat as if fertilzing the area and their own nostrils.

(v) - Same as above except on a larger scale when one can not wait till they get to the bathroom and begin their emmissions from some point outside the bathroom. This person will often fertilize more than their own nostrils.
"Man....after all that Chinese food, my butt was crap dusting all the way to bathroom!!"

Thanks to Rob and Big. Like Crop Dusted...but not.

When someone walks in front of an unexpecting victim and farts...the person then begins to notice the crime.

Could also be called a drive-by pant bomb
