The Denver Dripping Donkey Doorknob is when a man ejaculates onto a doorknob and waits on the other side until someone opens the door. When the other person walks through the door the man pulls down his pants, bends over. and defecate all over the person's crotch
"Aw man someone totally pulled the Denver Dripping Donkey Doorknob on me. There was cum on my hands and shit all over my penis."
