Cách sử dụng
The expression "put up or shut up" means that if someone is making a claim or a challenge, they need to back it up with actions or evidence, or they should stop talking about it. It's often used in situations where someone is making an empty or boastful statement and is challenged to prove it. For example, if someone says they can do a particular task better than anyone else, someone might respond with "Put up or shut up" to challenge them to perform the task and prove their claim. It's a way of saying that talk is cheap, and actions speak louder than words.
