Poop molded into a worm
A faggots game, after butt sex, they grab their dicks and sqeeze out mud worms.
Mudworm: a long brown turd. mudworms are mostly indigenous to the dank confines of the cities sewers, but some time they can be spotted in the wild. sometimes they sit poised; curled on themselves like a frosty ice-cream cone, or a venomous snake ready to strike. It is not advised to pick up or handle these creatures- unless you are German, or two girls with one cup
