Tranny Shit

When an obese truck driver is too lazy or too fat to get out of his truck to go take a shit and doesn't have a plastic bottle big enough to contain his feces or just doesn't have good enough aim to shit in said bottle so he instead just cuts the rubber boot around the shift lever on his transmission and takes a shit on top of the transmission. This also applies to truck drivers that may not be obese but are either afraid to get out of their truck or not willing to pull over to take a shit. These drivers are especially talented because they can simultaneously shit on their transmission while driving, shifting gears and watching porn on their smartphones.
