If you live in Sweden you just wouldn't want that plate on your car... Let me explain it like this:
If your name is Nils in Sweden your nickname would be "Nisse". If Nisse happens to be a whore his nickname (in a bad way) would be "hor-Nisse" which is just as good spelt without the "-".
But I think that the word is actually german for "hornet" which sounds alot better than the swedish translation....
