Following on from the PPP tread "euphemisms", one I dislike is the the question "may I use your bathroom?" or to use the word "bathroom" when you really mean "toilet". Someone mentioned it a few days ago and someone else replied "if you want to have a crap use the toilet, it's hard to flush turds down the bath plug".
And the tale doing the round s a few years ago, where dippy blonde goes to new boyfriend's house where they have a small wash room with just a small sink under the stairs. DB want to have a wee so asks to use the washroom. A few moments later there's an almighty crash as the washbasin is ripped off the wall....
