Taffing

The act of making a noise by hitting your abdominal muscles with your penis. For best results, one needs 1) to lie down and 2) to have a semi Flaccid or erect penises do not work so well as the former is too soft to make a loud enough noise and the latter is less mobile. A group of 'taffers' may be able to create beats as each taffer will usually create a noise with a slightly different pitch to that of his fellow taffers.
