A sneer is a facial expression that conveys contempt or disdain. It often involves curling the lip or raising one side of the mouth, signaling disapproval or ridicule. This expression can be a non-verbal way to communicate negative feelings toward someone or something, indicating that the person feels superior or dismissive. In social interactions, a sneer can create tension and conflict. It may be used to belittle others, making it a common feature in competitive environments, such as sports or politics. Understanding the implications of a sneer can help individuals navigate complex social dynamics and improve communication.
