POMA
POMA (PISS OUT MY ASS) is an acronym associated with severe bouts of extremely loose, almost liquid diarrhea which exits the victims asshole at near the speed of light similar to a giant stream of a feces infused urine that cannot be held back after a undeterminable point in time. Thus a victim of POMA may or may not be able to hold it back until the they reach a toilet, hide, or protect others from the god-awful stench.
