Hiligaynon
To gnash one's teeth, to grind the teeth, to strike or dash the teeth together in anger or pain. Ang yáwà nagabágrot. The devil gnashes his teeth. Indì mo akó pagbagrotán. Do not gnash your teeth at me. Bagrotá lang ang ngípon mo. Just grind your teeth. Ang amó nga balítà nagpabágrot sa íya sa dakû nga kaákig. That news made him gnash his teeth in great anger. (see báglot, which, however, is seldom used).
