An affectionate name for a vehicle that spews shit out the back as fertilizer for farm crops. These smell so terrible that you will start gagging the moment you open the car window 20 kms away (depending on wind direction of course). If you thought skunks were bad, imagine the poor soul that may slip into the soil by accident while directing the stream of animal feces, smack dab in the middle of fertile canals of life-giving liquid.
