The expression "blow the whistle on somebody/something" means to report or reveal someone or something that is doing something wrong or illegal. It is usually used in situations where the person reporting feels a sense of responsibility to speak up and expose the wrongdoing. For example, if someone notices that their coworker is stealing from the company, they might decide to blow the whistle and report the theft to their boss. This expression is often used in the workplace, but it can also be used in other contexts where there is a need to report wrongdoing, such as in sports or politics.
