facedesk
Like facepalm and headdesk had a baby and it was born screaming in a trash can because the comment was that stupid.
When my friend said the sky is pink, I did a facedesk and then a facepalm.
She said the moon is made of cheese. I facedesked and then cried.
He told me I was ugly and I facedesked so hard my face turned red.
