Gerbilling
In Poland, World War II historian Marek Jan Chodakiewicz lectured on gerbilling at the Institute of National Remembrance's educational center, describing that his ex-girlfriend Debbie, a registered nurse, extracted a fat-smeared hamster from the rectum of a gay man in 1984. Polish media stated that the hamster story is a well known urban legend, so well known that it has a Wikipedia page.
