hippopotamus doorknob 

Noun. A process in which a person shoves an umbrella in his or her anus, and then promptly opens it up, thus making his or her asshole larger. The misguided soul then proceeds to put watermelon-sized anal beads into his or her rectum. This being must then try to regurgitate these objects into a friend's mouth. Finally, the friend runs to the nearest zoo naked and gets impaled by a rhinoceros.

- Damn son, why you so stressed today? Did ya take a hippopotamus doorknob recently?
- Yes, my anus is still sore.
- I'm sorry for your loss.
