Lion Face 

The yawn-like jaw spasms you get the day after rolling and grinding your teeth too much. The most frequent and powerful faces are made when you didn't have gum or a binkie to curb the jaw grinding.

Me: I've been making this stupid Lion Face all fucking day!

You: That's why god invented binkies.
