The term "thumbs down" is a gesture commonly used to indicate disapproval or rejection. It involves turning the thumb downward while the other fingers are held upright. This gesture has ancient origins and is often associated with the Roman gladiatorial games, where it was believed to signal that a defeated gladiator should be spared or killed. In modern culture, "thumbs down" is frequently used in various contexts, including social media and film reviews. It serves as a quick way for people to express their negative opinions about something, such as a movie, product, or idea, often alongside its counterpart, the thumbs up gesture, which signifies approval.
