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.
