usage

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'
