While mooning someone, the mooner bends over exposing his dick and balls. He then sways back and fourth as to make his dick look like the long pendulum on a grandfather clock

Awesome guy, he lives near Buenos Aires and speaks Spanish with a central European accent. His closet is full of brown suits. He used to be an electric repairman in the 40s. His favorite drink is Fanta and his name is "Heinz von Schrettenberg"
My Argentinian Grandfather from Buenos Aires just called and said that Fanta is the "superior beverage"
