Cropdusting

[Rihanna]

The act of starting at one end of a person-filled room, ripping a nasty fart (the thick ones are better, as they cling more), then moving briskly to the other end of the room, staying ahead of your own stench, yet dusting the rest of the room with your flatulence.

[Marquetta]

The spraying of powdered insecticide or fertilizer on crops, especially from the air.
