: to show or exclaim surprise, wonder or astonishment
Used at the beginning of any question or statement to show surprise by something or someone. The greater the surprise, the longer the Waa should be, to indicate the degree of surprise.

3. Waaaaaaaaaa! Since when? (on hearing the news that Microsoft had decided to give away Windows for free!!)
