A phrase originating in Britain/Australia, frequently used in BBC comedies. (Some good examples of shows where this phrase is used frequently are Little Britain, Red Dwarf, and The Mighty Boosh.) Depending on the severity with which one utters the phrase it can mean one of four things;
1. Be quiet
2. Go Away
3. Go fuck yourself
4. All of the above

An excellent substitute for the phrase 'go fuck yourself' if you are in the company of small impressionable children, the elderly, or any other wanker who is offended by swearing.
