"Sag off" is a British slang term that means to skip school or work without permission or a valid reason. The term can be used in a variety of contexts, but it typically refers to when someone is supposed to be at school or work but instead decides to skip it. For example, a friend might say to you, "Are you going to sag off tomorrow?" meaning, "Are you going to skip school tomorrow?" It is important to note that this expression is not commonly used in American English.
