The process of taking any male human being and grabbing the shaft of his penis and pulling it up and tying it around his shoulder. If the genitalia has not ripped by this point, you proceed to take the man and turn him on his side and strum on his stretched out penis as if you would do on a banjo making very melodic and beautiful sounds.
Jeff: Man! This song is so soothing.
Mike: Of course it is, it's made using one of the most beautiful instruments on earth.
Jeff: What would that be?
Mike: The Weener Banjo, of course!
