BJ Piledriver
When a guy is in a standing 69 with a lady and just as he cums he thinks, “What the hell,” and piledrives her head into the floor.
I know this guy who got arrested for giving a chick a piledriver while she was blowing him upside down. Pretty impulsive thing to do, but he’s a legend who goes by the monicker of BJ Piledriver.
