British Dictionary definitions for fanny

fanny
/ (ˈfænɪ) /

noun plural -nies slang

taboo, British the female genitals
mainly US and Canadian the buttocks
C20: perhaps from Fanny, pet name from Frances
Despite the theory that this word derives from the name `Fanny', its use in British English is still considered taboo by many people, and is likely to cause offence. In the US the word refers to the buttocks. Serious misunderstanding may therefore arise when what people in Britain know as a `bumbag' is referred to in the US as a `fanny pack'
