Iron Butt

The Iron Butt is a large device, used as a replacement of one's butt. It is a large gray and dark blue machine with many wires, gears, pipes, lights, and other things sticking out of it. Concept-wise, it is a machine that doctors use in Bikini Bottom if a patient's butt is severely injured.

The Iron Butt is a parody of a device called the "Iron Lung," which was used for breathing problems because of Polio and Botulism.

“One more injury like that and you could wind up like that poor creature there, in the Iron Butt.”

“Oh man, it itches!”

Bonus Butt

When the fatty tissue of an individual's lower back is pressed together by the waste belt of their trousers, giving the appearance of an abnormally long anal cleft, or "Bonus Butt".

The phenomenon is frequently observed when an overweight individual leans forward while wearing a short T'shirt. Bonus Butt sightings are often reported at Ikea and other discount furniture stores, where the obese can be seen plopping and rolling around on various furniture items.

"Gross. I just got an eye full of Tammy's Bonus Butt."

"Don't bother. Nothing in there but boomachs and Bonus Butts"

"That is a tasty Bonus Butt. Yum yum yum."
