Now, I've got a good vocabulary, and between years working in heavy industry and the Australian Armed Forces, I also have a reasonable working knowledge of Australian slang and profanity (although I don't use it myself). But I've never seen or learned so many new words since I joined Netrider. Where do they come from?? For example, who coined the word 'numpty'? How did it come about? And what other words do you see on Netrider that you tend not to see elsewhere??
