When a girl sucks your dick and you tell her you’re going to nut in her mouth but you secretly aim for her nostrils, filling them with your sticky baby batter.
“Yeah, this girl I met on Tinder came back to my placelast night. She gave me a BJ and I totally pulled The Dirty Charles on her.”
A fetish that appeared in the Roaring 20's. The act involves a man paying a prostitute to shoot human excrement at him out of a trombone as he dances the Charleston naked, in a public square.
