facepalm dab
You hit your face so hard while you’re dabbing that you might as well just quit and go home.
I facepalm dabbed my brother when he tried to dab and it looked like he was trying to fight a ghost.
I facepalm dabbed my friend when he tried to dab in the middle of a math test.
I facepalm dabbed my dog when it tried to dab and it looked like it was trying to beat me up.
