When a person (or animal-- see below) defecates directly into the anus of a willing
sexual partner. This is
accomplished by both partners getting on their hands and knees, or laying on their backs with legs in the air, with their buttocks pressed together. With a lot of patience and experience, an expert pitcher and catcher can oftentimes maintain a back-and-forth for hours of pleasure.
It is widely debated whether or not the
Tootsie Roll Exchange happens in nature, or if it is a man-made creation; this has caused a rift in the animal sex-science community, spurring many heated arguments, and even one slap-fight at the annual Animal Sexuality-Science Convention in Zurich (citation needed).
