happy mouth

A mouth where, even at rest or during a state of neutral emotion, it appears to be smiling.

The corners of the mouth always seem to be at least slightly higher than the mid-line ("equator") of the lips like you're either partially smiling/smirking or are ABOUT to smile/smirk...

A lot of times this condition is accompanied by dimples...

Gina Carano appears to have a case of happy mouth. It makes sense since she is one of the best fighters in the world and one of the hottest fighters in the world. Palabra.
