Phone sign

From Wikipedia, the free encyclopedia

The phone sign is a hand gesture made by extending the thumb and pinky finger while keeping the three middle fingers curled and using one's hand as if it was a phone: the thumb is placed next to the ear and the little finger next to the mouth. This gesture is a common way to silently tell someone to call him or her such as to continue a conversation in private, or that a call has arrived for them which they should go answer.
