When you yawn and you get a painful cramp in your jaw/neck area. Sometimes it's so bad that you cannot close your mouth for a bit. It's called cocksucker's cramp because of the expression one does after yawning when he/she realizes she got a cramp it that area.
Chad : Matt yawned and his mouth stayed open for like 2 minutes.
Dan : LOL, Cock Sucker's cramp!
