A: The movie will open in 20 minutes. Chop, chop!

    B: Hold your horses, we still have some time left. We can get there in 10 minutes at this time of the day.

    Note: This idiom means to “be patient.” It is an American idiom that harks back to the old days when wagons driven by horses were roaming the roads. When the horses started to run, galloping away in full speed, it would be in vain if you recalled something else for the messenger to do for you. People would tell the messenger to hold his horses so they could make sure there’s nothing amiss. To tell someone to “hold their horses” is for them to hold on, be patient and wait for a while.
