The act of flossing one's teeth with the hair that is near or on the asshole of one's partner, so that the "chuncher" receives a tooth flossing and the "chunchee" receives a dingleberry removal. Because of the mouth-to-asshole proximity that is involved, a chunch is often accompanied with a friendly rimjob or an ass trumpet.
