Yea sure. Here's a great one: Why not just call it "one dollar"? Why do we have to have a stupid name for it?
Before the introduction of the one dollar coin none of our other coins had bizarre made up names.
Well dont be making fun of our canadian currency. I very much prefer it over american currency. The number one reason is we actually have life in our money. I am sorry to say, but green is boring. Also the bills are better when different colours because it allows you to tell them apart.
What other names do you suggest? Its no different then calling one of your bills a lincon. Seeing as our coin has a loon on it, a loonie is appropriate. I dont see anything wrong with such names or how it evokes hilarity.
