Have Your Heart in Your Mouth

Etymology:

• Many years ago, the famous poet Homer used this expression in his poem The Iliad. When you are extremely scared about something, your heart beat gets faster and you feel something clogging in your throat. Homer expressed that feeling of dread as having “your heart in your mouth”. Later for centuries, many people used this expression when they found themselves in a panic situation to describe their fright and terror about that thing.
