This phenomenon mostly occurs in summer. When a person is naked and lying face down on the bed during sweating, the farts will spray sweat from the buttocks into the air, and the sweat loses heat as it moves through the air, reducing the temperature to below body temperature. Eventually, when the below-body-temperature sweat falls back on human skin (mainly the thighs), it creates a chill, and this phenomenon, known as Asscano Eruption, is perceived.
