Bulgarian Shit Twister

When a woman squats over a man's meat stick while he is laying on his back, then unleashes a slightly loose dump similar to oatmeal. The woman then proceeds to insert the man's shlong into her anus and bounce on it while performing a plethora of consecutive 180 degree spins after each bounce; using her feces as lube.

Dude. Your mom gave me the best Bulgarian Shit Twister last night after your birthday party.
