What is Pepper The Tailgate?
A gruesome act that originated in Sidney, Nebraska where a person who is experiencing explosive diahriha (an intestinal disorder characterized by abnormal frequency and fluidity of fecal evacuations) drops trouser, bends slightly at the waist and procedes to unleash "pepper" on anyone's "tailgate" that is nearby. This is usually done at drunken field parties in Western Nebraska as a form of entertainment.
"Hey me and ol' Ramrod are going out to Sidney tonight to play pepper the tailgate, you in?"
"Sure, I love playing dodge the explosive diahriha."
