The term "impertinent" refers to behavior that is rude or disrespectful, often characterized by a lack of proper manners or consideration for others. It can describe comments or actions that are inappropriate for the situation, making the person seem insolent or cheeky. In social interactions, being impertinent can lead to misunderstandings and conflicts. For example, if someone interrupts a conversation with a sarcastic remark, they may be seen as impertinent. This type of behavior can damage relationships and create a negative atmosphere in both personal and professional settings.
