Face-cracking
When something shocking happens and your face looks like it’s about to explode from the inside out.
When my ex posted a picture of me eating a taco with a burger on top, I face-cracked so hard I nearly fainted.
My friend told me he dated my crush and I face-cracked so bad I had to leave the room.
When I saw my dog wearing a hat, I face-cracked like I just saw a ghost.
