A Joony Dupe is the act of a man standing in the position, similar to that of Captain Morgan, with his left hand raised in the air. His left hand is then coated with both peanuts and peanut butter. A third party then lowers a man or woman's anus onto said left hand, until they can go no further.
Man, last night, my friends and I got high on some ecstasy and ended up giving a Joony Dupe to my girlfriend!

Don't eat that peanut butter! I hear Hal and his friends used it for a Joony Dupe last weekend!
