Whistling up a pig’s ass 

This expression was originally by Rednecks in the USA, but achieved wider recognition and usage due to combined operations between the US Army and British troops. It is used to describe something that is totally futile, a waste of time and effort and something you do not wish to do. By extension it can also be used to mean a person who is a waste of time and resources, someone with whom you do not wish to associate, that the world would be better off without and who is one of nature’s biggest mistakes, in short a complete and total Malcolm.

Malcolm has just fucked the system again, that waster is no more use than whistling up a pig’s ass.

waffling 

Excessive talking, sometimes to the point where it gets boring and drags on for way too long, aka rambling.
It's a slang word used in Britain, but mainly in London or other parts of England by roadmen / younger generations.

"Bro my Psychology teacher is so boring, they're always waffling about nonsense that has nothing to do with the lesson."
"I definitely failed that History test, I just waffled tbh."
"That Biology question was so long and irrelevant, there was so much waffle in it I barely knew what they were asking me to do."

Hiring a prostitute to whistle 'Rivers of Babylon' up a mans anus, whilst jiggling his balls like a coin bag.

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..
