hoser
Hoser: Canadian hockey derogatory term that is similar to the American "idiot" or "loser". It is derived from the pre-zamboni days, where the losing team would have to hose down the ice after the game.
Take Off to the Great White North, by "Bob and Doug Mackenzie," (Rick Moranis and Dave Thomas) was a novelty song from the early 80s, which mocked Canadian culture and slang terms like "beauty," "good day," "eh?" and "hoser" or "hosehead."
