A recently discovered parasitical worm. Closely related to heartworms in dogs, it lives similarly but in the rectum of humans. Where its habit of multiplying until there are so many worms they block passage of stool, a necessary occurance for successful buttworm breeding. As the turds get jammed in the colon, the buttworm releases various rapid-acting enzymes and bacteria that rapidly turn the fudgepack directly into high pressure gas, often in seconds. The high pressure gas can be released in a lethal explosion capable of knocking individuals several feet off the ground. When that has happened, Individuals caught unaware have been knocked out upon falling back awkwardly to the ground due to knocked senseless by the initial buttblast. The buttworm uses these ass-ripping blasts to spread its airborne larvae. Microscopic, it is breathed in. A brief rancid taste is the only sign this is happened. Once in the body, the larval buttworms migrate to the rectum to repeat the cycle anew.
