Using your tounge to push poo out through your gaps in your teeth to make pooey strings like a Play DohSpaghetti Factory. It may be your own poo or someone you do or do not know.
Similar to the Fabulous Larry, and a variation on the Cleveland Steamer. You defecate through a tennis racket and steamroll the feces through by pressing your anus down on the racket so the feces comes out the bottom as strings on to your partners chest. This is topped off by blood from the hemorrhoids on your anus which leaves it looking much like spaghetti with a red sauce on top. Sprinkling Parmesan cheese on top is optional.
