Klopapier?

Just now we are debating whether klopapier is pc to say. Ze Germans say that it is more speaking language than written language. Here in Switzerland it seems ok to say klopapier rather than toilettenpapier (both meaning toilet paper in case you didn't get it). Klo coming from water closet I suppose.

Yes, we don't have big problems here, having time to discuss trivia like this :)
