Thunder Biscuit's definitions
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.
