loony

1. short for "lunatic". A crazy person. This term is derived from the phrase "crazy as a loon".

2. in Canada this word denotes a 1 dollar coin that has a loon bird on one side. A Canadian 2 dollar coin, which has a polar bear on one side is called a "toony".

1. The loony is on the grass.

2. At the University of Toronto I talked to a student there and I mentioned seeing the word "loonies" on a video game in a bar nearby. I told her that in America a loony is a lunatic, that the word means that someone is nuts. She said it used to mean that in Canada too, but the meaning changed when the coins were introduced.

Loony

Goofy, crazy.

I guess it could also mean 'like a loon (the bird)', but what would that be saying?

Mick: Steve's acting a little loony; now he's always talking about this get-rich quick scheme that he brought home from work and how he really wants each of us to have a piece of it. I'm not sure if he's joking or what.

Stan: You can never tell with that guy.
