If you're ever at a loose end and feel that a few more euphemisms for rude acts would fill the empty hours when you aren't actually committing rude acts (or eating, sleeping, working or otherwise doing anything constructive), then The Always Amusing Euphemism Generator is probably the site for you! Of course I am only using it because I am too tired to think up my own dirty phrases - normally I could do a whole lot better...
