Facepalmist
A facepalmist is someone who is so clueless it’s like watching a train crash. You just know you’re going to have to slap your face every time they open their mouth.
My friend said, 'I think the moon is made of cheese.' I facepalmed and almost fell over.
My mom said, 'I think dogs are just cats who failed.' I facepalmed so hard I got a nosebleed.
My dad said, 'Why is the sky blue? Because it’s tired.' I facepalmed and got a crick in my neck.
