tsk

used to express disapproval, disappointment, or annoyance

The pronunciation of "tsk" involves a quick, sharp sound made by pressing the tongue against the roof of the mouth, near the front teeth, and then releasing it quickly. It's essentially a clicking noise produced by the tongue. Often, when people say "tsk," they also shake their head slightly from side to side or raise their eyebrows to emphasize disapproval or annoyance.
