Talk to the Hand

"Talk to the hand, because the face ain't listening!"

Sometimes a person is just done with the discussion or argument. They don't want to hear any more chatter or whining or arguing. So when the other half of the conversation tries to keep going, the first guy cuts them off by thrusting his palm in front of their face as if to stop any more words from being spoken.

The full "proper" way to do this is to turn away while sticking your arm out away from you to show the person you're trying to shut up your palm, coupled with the phrase, "Talk to the hand!" Another variation is to turn around completely and even start walking away with your arms raised and showing the other person the back of your hand. Either way the message you're sending to the other person is essentially, "Talk all you want, I'm not listening." in a rather contemptuous manner.

The gesture itself is quite old; the words were popularized by the 90's sitcom Martin, being used extensively by the titular character.

Not to be confused with Talk to the Fist.
