Facepalm
Facepalm (you’ll also see it spelled as two words: face and palm) is a new word that describes the act of covering your face with your hand when you’re in difficult or uncomfortable situations. It’s a pretty natural thing to do when we’re feeling embarrassed, frustrated or very disappointed.
He had to facepalm when his boss pointed out typos in his report after he’d checked it three times.
