A type of human turd that results from clenching the buttocks at the beginning or end of a long drawn out bowel movement. The pancaking action of the ass cheeks on either end of the poop tube creates a distinctive hood. Thus transforming an ordinary butt snake into the butt cobra.
Man the other morning I sneezed while I was taking a shit! I totally tamed that butt cobra.
