Facial Cramps
Your face turns into a meat grinder because you’ve been grinning like a madman or trying to look sly for too long.
My face feels like it's been run over by a pizza truck after the whole class laughed at my joke.
I had to smile through 10 minutes of a bad YouTube ad and now my face is in pain.
I tried to look like a spy for my friend’s prank and now my jaw is broken.
