Highly Combustible Fart Syndrome

An uncommon yet highly infectious disease characterised by the repetitive and highly explosive detonations released from one's rectum, often coinciding with a massive expulsion of shit and piss (shiss, or pisst if you prefer). Strangely, the sizes of the sudden shit-splosions have been measured to be over 10 meters long and contain more force and matter than the unfortunate individual could possibly house. Despite the disease being almost impossible to investigate, it is thought that the sudden force of explosive diarrhea rips a hole in the fabric of the universe, creating a small temporary wormhole allowing more shit to travel through. Some scientists theorise that if the disease was more closely understood, it is possible that it could hold the key to both interdimensional and warp-speed travel.
The exact origin of this disease of this is unknown, but it is theorised to either have been caused by the founding of Taco Bell in 1962, or the popularisation of commercial laxatives in the late 1920s.

Anal Combustion

Any form of explosion just inside the anus. Could be the result of inserting and igniting gasoline or gunpowder, attempting to light a fart, or that Mexican food from yesterday. Depending on the strength of the sphincter, severe anal combustion may result in blowing out the anal socket or rupturing of the rectum.

I had pretty bad anal combustion after that spicy 15 bean soup--it almost blew out my sphincter!
