I'm looking for a verb to describe a noise that people make when they are dissappointed. It is made by pulling the tongue away from the back of the teeth and can also be made in a similar fashion with the side of the cheek. It is high pitched, sharp, but can also be dragged out to have an almost hissing noise. I wouldn't really say it's "tsk"ing or tutting. An example of when someone would do this is when they're playing basketball and happen to miss a shot that they usually make (say a free-throw). Please help me find the correct word for this action.
