Get the Fart Boxingmug. An event where two people trade off cracking farts until one is either out of farts or can no longer stand the smell of his opponents flatus.
Wayne was defeated in an early morning fart boxing match when he admittedly could not take the smell of Joe's bout winning spinach fart.
