Sign of Displeasure is a term used to describe facial expressions that indicate disapproval or dissatisfaction. A GRIMACE is a facial expression of disgust, pain, or displeasure, usually characterized by a contortion of the features. A SNEER is a facial expression of contempt or scorn, typically showing one's teeth and involving a slight raising of one corner of the upper lip. Both GRIMACE and SNEER are common signs of displeasure.
