As a Professional Shitter who specialises in the occult, allow me to explain. In attempting to produce a comedic asmr video, the sounds that the boy made seem to have accidentally imitated an ancient shitting ritual, a shitual if you will, and contacted the spirits that dwell in the bowels.
This particular shitual was commonly used in ancient Aztec culture as a form of ceremonial bodily purging, and was believed to purify one's soul through emptying the body. Despite the supposed merits of this shitual, it is certainly not painless, and as such was abandoned and lost to time.
