A term used to describe a particular and severe gurn (a distorted facial expression, caused by various drugs, resulting in a grotesque face and in some cases, the jaw action of a jackhammer).
An individual displaying a savage 'Godzilla Gurn' may almost appear to be a dinosaur, due to his or her display of ferocious jaw power, locked facial expression and huge glaring eyes. Unlike a normal gurn where the jaw is contorted into numerous positions, 'Godzilla Gurn' subjects appear to have fixed clamped jaws.
