Mongolian Chimney Sweep 

The sexual act in which, after a thorough reaming of a ladies ass, you flip her upside down and poop into her gaping butt cavity.

Last night I gave that skank whore the old Mongolian Chimney sweep and got crap all over the hotel.

Mongolian Chimneysweep 

A sexual act performed following anal intercourse, where the person who was being penetrated does a head-stand exposing his/her gaping anus and the penetrator sits atop the penetratee and defecates into their rectum.

The Mongolian Chimneysweep requires some degree of flexibility.
