Gerbilling
__NOTOC__ Gerbilling, also known as gerbil stuffing or gerbil shooting, is a rumoured sexual practice of inserting small live animals (usually gerbils but also mice, hamsters, rats and various other rodents) into the human rectum to obtain stimulation. Some variations of reports suggest that the rodent be covered in a psychoactive substance such as cocaine prior to being inserted.
