combustication

synonymous with combustion, just a lot more enthusiastic. Invented by Julius Sumner Miller during a physics demonstration in 1969.

I don't like combustion. It's too quiet. I have some stuff in a state of combustication.

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.

Michael: Ah fuck man, the doctor has diagnosed me with Highly Combustible Fart Syndrome. He-

Spontaneous Cumbustion

The process by which, through the ingestion of an unruly quantity of phosphorous, one's ejaculate spontaneously erupts into flames upon expulsion from the penis causing widespread fear and panic.

Dave and Marie were dating until Dave's spontaneous cumbustion all over Marie resulting in a sudden case of the funerals.
