The term 'Expression of Displeasure' can be expressed in two five-letter words: SCOWL and FROWN. A SCOWL is a facial expression that conveys anger, displeasure, or frustration. It is characterized by a furrowed brow and a downward turn of the mouth. A FROWN is a similar expression, but it is less intense than a SCOWL. It is usually used to express disappointment, sadness, or disapproval. Both expressions are nonverbal ways of communicating displeasure.
