This look is like someone's mixing a cocktail of sass and surprise. One eye is squinty, the other wide open, with a tongue sticking out like they're trying to say 'I dare you.' Throw in a death stare that means 'you did something bad, but I'm too cool to shout about it,' and you've got this face. You'd see it in arguments over who broke the vase or when someone steals your fries.
