gerbilling

Having a live rodent or small animal (usually a gerbil) and using some sort of tube, forcing the gerbil into ones asshole. No medical case has ever been recorded of someone needing to remove a gerbilfrom ones anus, so we must now come to the conclusiion that either a) gerbilling doesnt exsist. B) they are very good at getting the thing out afterwards. Gerbilling has many famous cases, such as richard gere reportedly having a wild session with the furry animal. For more information i recommend the south park episode "Death camp of tolerance" which features rather detailed examples of gerbilling.
