When taking a large shit and it hits the water with such force that the water comes back and splashes your cornhole.
Victoria had chipotle for lunch and multiple alcoholic beverages the night before. The combination of beer shits and chipotle had her prairie dogging until she finally reached the toilet. While unleashing the cracken on the can, the shit splashed the water with enough weight for the water to splash back up and hit her butthole. To which she reacted, "Ah how refreshing, the ole accidental bidet."
