body harmonica

When you go down on a chick vigorously shaking your head side to side like a rabid dog

I play the body harmonica like a toothless homeless man would eat corn on the cob.

When two biological males stand front to front and skotch tape their dicks together. (As supposedly done by Marilyn Manson and Twiggy Ramirez when they wanted one girl to give them both head.)
