A: Have you heard it? The Smiths won the jackpot.

    B: Really? I had no idea.

    A: Their arrival in a stretch limousine set the neighbors’ tongues wagging yesterday.

    Note: The idiom means people are gossiping. For example: Tongues wagged when another police car was parked in front of their house. This metaphoric expression transfers the rapid movement of the tongue to idle or indiscreet chatter. It first appeared in the 1500s. There is a similar saying in Chinese.
