The phrase "tell off" means to scold or reprimand someone for their behavior or actions. It is generally used when someone has done something wrong or unacceptable, and you want to express your disapproval or disappointment. For example, a teacher might tell off a student for not doing their homework, or a parent might tell off their child for talking back. It is important to note that telling someone off can be confrontational and may cause tension, so it should be used carefully and with tact.
