The term originated from Shakespeare's play "The Merry Wives of Windsor," in the 16th century. It is a term used in polite society to mean the Devil! (It has nothing to do with Charles Dickens.) The word appeared in a sentence (although sounding odd in modern day language) "I cannot tell what the dickens his name is my husband had him of."
Similar but differing slightly to the term 'twat', a Dickens is a pompous and awkward bastard who will go out of his way to needlessly berate his fellow man. Owing to the Dickens' overinflated sense of self importance the term is almost exclusively applied to ex public school boys. Often a Dickens will have been subjected to repeated bummings as a choir boy resulting in frequent pegging throughout his adult life.
