1. A shit so powerful in magnitude that it absolutely incinerates your butthole. It burns so much that a loud and often thunderous roar will come from you as it's happening, much like Pompeii.

2. A shit so powerful in magnitude that every living being within a mile of your toilet will feel/smell it. Screaming and cries for help will ensure, and prayers to God will be made because of that shit.
