Rectum-fish 

A suprisingly large gruesome parasite that situates itself on the overhanging skin of a persons arsehole. It lives off the juices slowly secreated through the bumhole, and its lifespan it approximatly 7.6 years! Being harmless itself, a rectum-fish can however, cause accute discomfort to its host, if it has been sitting down for long periods of time, as this restricts it's oxygen supply, making it squirm.

Man: I gotta go to the doctors' later today, I've gotta a bitch of a Rectum-fish sucking out my guts.

Rectum Rolled

To be tricked, through any method, into clicking a link that takes you to a picture of a weightlifter's prolapsed bowel hanging from his rectum.

Ken't colleagues and friends grew weary of his countless efforts at forcing them to view the weightlifter's insides, yet Gilbert was successfully rectum rolled on several occasions.
