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..
