- n. Nothing (sanitized version of fuck all).
From Fanny Adams (1859-1867), a young girl brutally murdered and dismembered. Tins of mutton introduced in the British navy after her death were not liked by the sailors and were taken to be her butchered remains. Fanny Adams then came to mean any worthless thing, and thence nothing at all. (Wiktionary)
