Bugger is a slang word used in the vernacular British English, Irish English, Australian English, Canadian English, New Zealand English, South African English, Indian English, and occasionally also in Malaysian English, Scots and (rarely) American English. It is derived from Anglo-Norman bougre, which has also given the term buggery, a term originally used to describe either anal intercourse by a man with a man or woman,[1] or sexual intercourse by either a man or a woman with an animal.[2] Today, the term is a general-purpose expletive, used to imply dissatisfaction, or used to describe someone or something whose behaviour is in some way displeasing, though in general Australian and New Zealand English the expletive force has largely disappeared; the word there now has a 'catch-all', almost humorous, 'Jeez' quality.
