Monaco mudflap

A romantic move believed to be invented on the streets of Monaco whereby a gentleman holding hands with his lady grips her hand tighter and pulls it close to him, pressing her hand against his anus while flatulating upon it. The gentleman’s trousers could theoretically act as a “mudflap,” allowing the lady to enjoy the vibrant warming sensation without the risk of fecal particles soiling her hand.

Talia was the recipient of the first known Monaco mudflap during a stroll on a beautiful summer night after spending the evening at the Casino de Monte Carlo.
