What is moue?

The word "moue" is a French term which refers to a pout or a slight grimace or a facial expression that usually indicates a mild displeasure or annoyance. It is usually made by pursing the lips, or by frowning, or by wrinkling the nose and is often a non-verbal way of expressing one's disapproval or disappointment. The moue is often used in comedy or satire to exaggerate a character's emotions or to add a humorous touch to a scene. The term is also used in facial recognition technology to describe the movement of the lips and the nose, and has been used in the development of advanced human-computer interfaces.
