The Importance of Numpty

I think that could be one of those words that's very, very Australian slash maybe English. I don't know if the English use it that much, but I definitely know it's not American because I've had to explain that word to so many Americans. It's kind of a word that someone will yell out of a car, you know, if you cut them off. That's pretty Australian, isn't it? I think it was. But it's hard because you just use them so frequently. You just think, um, yeah. Using everyone uses this, uses more on.
