lts to refer to someone who has done something stupid or has a history of stupidity. Or sometimes used to refer to other Canadians.
The proper reference to one who plays the Hosaphone(tm) is a hoser. If you don't perform on the beloved, revered and mostly plastic Hosaphone(tm) yourself, it is considered poor form to use this intimate address. Brother and sister Hosaphoners affectionately refer to one another as hosers.
Hey, hoser, how are you doing?
That's some mighty fine playing you did on, "Codetta in C" for Hosaphone(tm), Piano & Bass, there hoser!
If we could find a hoser for our brass quintet, we could accompany a Hosaphone(tm) Soloist.

A couple of hosers wrote this wonderful FAQ on the Hosaphone(tm).
