I never understood the word fanny pack, as if if was carried the other way around.
Ok, this is my theory, and be warned, more potentially offensive verbiage below.
I believe the term "fanny pack" started in England. On a trip to the UK I was told that over there, they call a woman's "front" her fanny. Apparently it's an offensive term there, much like the American slang term that starts with "P" and to quote a rap song "is another way to call a cat or kitty."
think "pussy willow".....
I always wondered why we called it a "fanny pack" here when it's worn in the front, but over here some people will refer to their rear ends as their "fanny".
This really makes me laugh, but I have a friend out in LA who refers to his bag as his "pussy pouch".
