..Japanese gestures..?

Tilting the head to the side while sucking air through the teeth can be loosely translated as "Sore wa chotto." which could either mean 'no' or just show uncertainty as to exactly what to do. For instance, I was playing golf with a friend a couple of weeks ago and when he walked up to his ball and found a tough lie, the head went to the side and air was sucked through his teeth. "Hmmmm, what to do here?"
