A term used to describe extremist members of volunteer fire-fighter groups. A hoser is one who holds the hose, while the actual firefighters are doing the real work. They frequent local coffeeshops till the wee morning hours. They communicate by radio, even when in close proximity to one another. Their larger-than-necessary trucks are adorned with firefighting decals and various lights. Usually overweight, they are never at a loss for displaying their newest Motorola device.
Dude, why do all the hosers have to stare at people when they pull into Dunkin' Donuts? When will they ever get a life? Someone start a fire!

Canadian insult, nothing to do with hockey. As any young boy can tell you, the resemblance between a penis and a hose is obvious. Therefore anyone who is a "hoser" pisses on people, figuratively speaking
(Canayjan): "We all ponied up to buy a two-four, but Kyle deked off, and drank it himself. That hoser sure hosed us. What a hosebag." (Trans.): "We all chipped in to buy a case of beer, but Kyle stole it and drank it all by himself. That prick sure screwed us over. What a bastard."
