|1.||Riding the Horse Backwards|
When taking a shit, sitting backwards or facing the wall or toilet tank so that when the turd drops, it lands on the runway and not in the water.
This can be done to leave some serious stench as the whole turd and not just the tip is fully exposed to the air, or just to leave a present firmly attached to the bowl for the next person or owner of the shitter.
Dude 1: "What the fuck is that stench coming from the shithouse?"
Dude 2: "Some asshole dropped a duece riding the horse backwards so the shit didn't go down."
