Thunder Biscuit

A Thunder Biscuit is a fart let out with such a force that it causes your buttcheeks to clap with a thunderous noise while simultaneously causing you to involuntarily deficate yourself releasing a sewage like gas into the air causing the surrounding area to become uninhabitable momentarily due to its longer than usual hang time.

Robert let out one of the nastiest thunder biscuits have ever smelt.
