face lag
Face lag is when your face looks like it’s been run over by a truck. It only happens to people who are too dumb to know what’s going on.
My teacher’s face lagged when I asked why the sky is green. It was like she had no idea what was happening.
During the exam, my face lagged so much, I looked like a confused zombie.
My sister’s face lagged when I said I got an A. It was like she saw a ghost.
