The act of consuming food through your anus, rather than your mouth. In this twist, you would result in crapping out of your mouth instead of your anus.
"You see, food entering through the anus has the benefit of being broken down on its way to the stomach rather than afterward. And therefore I believe that interorectogestion would actually put a stop to high cholesterol and most kinds of stomach cancers. And I base that on absolutely nothing." -The Surgeon General from South Park
