Intense diarrhoea, resembling a volcano. So intense that when fecies exits, it does so at such speed to cause a splash in the toilet water which makes contact with the buttocks.
n. An uncomfortable and often daylong affair during which one's bowels feel as though they may erupt at any time, similarly to a volcano. Often accompanied by unusually noxious flatulence including a distinct "hot" feeling. Most of the time, even a full release won't actually bring relief due to the lingering burn and difficult-to-contain aftershocks.
