A glower is a facial expression characterized by a fierce or angry look, often involving narrowed eyes and a furrowed brow. This expression typically conveys displeasure, disapproval, or hostility. People may glower when they are upset or frustrated, and it can serve as a non-verbal way to communicate negative feelings without using words. The term "scowl" is often used interchangeably with glower, as both describe similar expressions of anger or annoyance. A scowl can be seen in various situations, such as during conflicts or when someone is displeased with a situation. Both expressions are common in human interactions and can indicate emotional states effectively.
