Here in the states we can buy a little ball of netting like material to be used to wash with in the tub/shower. We call it a poof. (Have also heard it called poof ball.)
In other countries (I know in Australia & the UK at least) 'poof' referrs to a gay person.
Now washing with a poof is a whole lot different then washing with a poof!! LOL

And if you look at poof ball....
Ball being a round object or the act of fucking....
Kinda slightly different don't ya think.
