- noun the female genitals. This old and relatively inoffensive euphemism is possibly derived from the well-known erotic novel, The Memoirs of Fanny Hill, by john Cleland, published in 1749, or is perhaps simply an affectionate personification of the sex organs, using the short form of Frances. The word is used by women as well as men.
- noun the backside, buttocks. The American sense of the word probably derives from the earlier British sense. Fanny is sometimes confusingly used with this meaning by middle-class speakers in Britain too.
