The term 'insolent manner' can be defined as an ATTITUDE of disrespect or defiance. It is often characterized by a lack of respect for authority, and a disregard for the feelings of others. This ATTITUDE can manifest itself in various ways, such as speaking rudely, making inappropriate comments, or displaying a general lack of courtesy. Insolence is often seen as a sign of immaturity, and can lead to serious consequences if not addressed.
