thumbs up Idioms  

1. An expression of approval or hopefulness, as in The town said thumbs up on building the elderly housing project. The antonym thumbs down indicates disapproval or rejection, as in Mother gave us thumbs down on serving beer at our party. Alluding to crowd signals used in Roman amphitheaters, these idioms were first recorded in English about 1600. In ancient times the meaning of the gestures was opposite that of today.
