1.
The face that one makes when expressing exuberance or extreme rage. Features include a widely-opened mouth, lowered eyebrows, partially squinted eyes, scrunched nose, and (usually) bared front teeth. Grazzle face is a term used to describe this common facial expression that, despite being familiar and well-known, has never before been named.
