Whistling up a pig's ass 

This picturesque expression was originally used by Rednecks in the USA, but has achieved wider usage due to combined operations of US and European troops. It is used to describe something that totally futile, a waste of time and effort and something that you do not wish to do. By extension it can be applied to mean a person who is a waste of time and effort, someone with whom you do not wish to associate and whose existence can only be described as one of nature's biggest mistakes..

Malcolm's made another great and glorious cock-up, that asshole really is no more use than whistling up a pig's ass!

Waubay Whistler 

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.

To create a whistling noise like that of blowing over a bottle, except using another person's shit hole. Thus a shit whistler. Can be used to imply someone is of a homosexual persuasion.

Mike in a childish voice up the stairs: "I've just turned all the items in your room upside down..."

A genre of music relating to the modern concept of hardcore music (it is also related to metalcore, emocore, grindcore, and many other "core" genres.)

The music is played primarily with screaming vocals and a whistle. Often it is merely 1 person whistling, then screaming.

Johnny is was totally headbanging to the awesome whistlecore, before he burst out laughing.
