Creating a bow like tie out of poop after you have pulled out of a girls ass while having anal sex with her.
The cincinatti bow tie is where you are fucking a chick in the ass and you pull out with a little poo on your doodle and then lay it on top of her ass crack and sway it back and forth so the poo spreads like a windshield wiper creating the bow tie with her balloon knot being the tie knot.
