facepalm index
How much you want to punch your face because everything is going wrong. The FPI is the number of times you facepalm like a confused idiot.
My dog ate my homework and I facepalmed like I was in a horror movie.
I spilled my cereal on my shirt and facepalmed so hard I got a headache.
My teacher gave me a zero and I facepalmed until my face was a red balloon.
