Captain Brownhead 

When a man sticks his penis in another person's anus, covering the head in shit, and pulls it out and mushroom slaps them across the face with it, leaving a brown mark on their head. It must be followed with the phrase, "YAR HAR! I BE CAP'N BROWNHEAD!!"

Did you hear that Sally got a captain brownhead from John???
