facepalm

A facepalm is the physical gesture of placing one's hand across one's face, lowering one's face into one's hand or hands or covering or closing one's eyes. The gesture is often exaggerated by giving the motion more force and making a slapping noise when the hand comes in contact with the face. The gesture is found in many cultures as a display of frustration, disappointment, exasperation, embarrassment, horror, shock, surprise, exhaustion, sarcasm, shame, or incredulous disbelief.
