Much like the sound of pinching the open end of a balloon and listen to the air whistle while it slowly exits. To perform the Waubay Whistler, you blow air into your woman's vagina. Quickly you pinch the labia together and allow the inside air to escape slowly. The resulting sound is a whistle of sorts emitting from the vagina.
I was bored whilst performing cunnilingus on my girlfriend, so I shook things up a bit and gave her a good ol' Waubay Whistler.
