Unpleasant particulars. The word gore, from Old English and German words meaning blood that had been shed and clotted, came to denote, by extension, murder, bloodshed, and other kinds of violence. It was so used by Dickens in Barnaby Rudge (1841), “Something will come of this. I hope it mayn’t be human gore.” Literally, therefore, gory details means “bloody details,” but despite violence being by no means obsolete, the term has been transferred to mean the unpleasant particulars of just about anything, ranging from a business transaction to a divorce. It is also used ironically for any details, whether pleasant or not.
