"Thumbs down on" is an idiomatic expression that conveys a negative or disapproving sentiment towards something or someone. The phrase has its origin rooted in ancient Roman culture, where during gladiatorial contests, the audience would signal their opinion on the fate of a losing combatant by using their thumbs. A thumbs-down signified the desire to see the losing gladiator subjected to a killing blow. Over time, the term has evolved to represent a strong indication of disagreement, disapproval, or rejection.

It conveys a sense of opposition, often accompanied by a negative evaluation or criticism. The expression may be used in various contexts, including voting, reviewing, critiquing, or expressing public opinion. For instance, a person might give "thumbs down" on a social media post to indicate dissatisfaction or disagreement with its content or message. Similarly, movie critics often use the phrase to signify their negative assessment of a film.
Overall, "thumbs down on" serves as a symbolic gesture representing strong disapproval, disfavor, or rejection of someone or something, and its cultural roots in ancient Rome add historical significance to its contemporary usage.
