A sexual toy that is inserted into the anus...preferably "vibrating". Often available with a "safety tether".

egg butt 

A particularly awful smelling fart from deep within the bowels. It has the distinct sulfur odor usually associated with rotten eggs.
Stan: Dude, did you just shit your pants?

Eric: Mmmm, no. It was just egg butt.
