Deldalech is the material once used to blacken teeth in Palau. When the deldalech was applied it was "eaten" by keeping the mouth and lips completely immobile for several hours until the dye had set. May be applied to a meeting at which some problem is presented for discussion and no discussion takes place, all the participants sitting in stony silence; also to a person or group that receives a reprimand in silence.
