An act of anal sex where the female (or male) has not used an enema before intercourse and purposely tries to defecate at the same moment of penetration, thus resulting in fecal lubrication of the rectal cavity.  Continued sexual intercourse causes the excrement to eventually engulf the entire penis and testicals of the man.  A position usually done in "scat" movies.

Get the Shitstained Ballsmug. A Russian Shitstain is when a guy slaps his shit covered paynus horizontally across a man's face, leaving shit marks that look like warpaint.
He tried to pretend the smudges on his face were Nutella, but the smell let us know that he was just the willing participant of a Russian Shitstain.

Get the shitstain waterfallsmug. Someone who brags and talks a lot of shit to appear big infront of his friends, gf, and buddies. Desperately trying to hide his own insecurties and believing in his own hype.
Tommy talks so much shit, and that fat fuck believes in his self hype what a talking shitstain he is. Always talking when no one wants to listen.
