Cebuano mumo (v)To hit your mouth with something (assuming it would cause swelling and bleeding).

It covers: * getting punched in the mouth * getting whacked in the mouth * hitting your lips with the spoon when eating * hitting your mouth on a hard surface like the edge of a table or the edge of a stairs' tread * diving and landing with your mouth * or you can get cheesy; accidentally slip and get *mumo* with some girl's mouth   Does not apply with slapping your mouth because you uttered a swearword. But if you intend to make your lips swell or bleed, with the slapping, that would count. In a sentence: * Nagtikuko sa kasakit ang imong mama kay *namumo* sa kumo sa imong papa.
