When it comes to using a PC, Her Royal Highness Queen Evelyne knows "Sweet Fanny Adams!" Summary of "Sweet Fanny Adams" The dark British expression "Sweet Fanny Adams" means "nothing at all." Here is its story in a nutshell: - The Tragic Start (1867): An 8-year-old girl named Fanny Adams was tragically murdered in England, making national news. - Navy Slang: Soon after, the British Royal Navy started serving unappetizing canned mutton. Sailors joked grimly that the canned meat was poor Fanny Adams. - Nothing Left: Empty meat cans held nothing at all, so sailors began using her name to mean "zero" or "worthless." Adding the word "sweet" made it an idiom. - Modern Use: Today, people use it (or the short version "Sweet F.A.") as a polite way to say "fuck all."
