A slur referring to Canadians. It finds its origin in the common practice of the same name in northern Canada
. Canadians living by themselves in cabins in the frozen north often grow very lonely during the long winter months. These Canadians then spread their food scraps outside of their cabin. Moose (and other animals) are attracted by the smell of this food, and the Kanuk
then proceeds to mount said Moose, often pleasuring himself hundreds of times with the same moose until springtime!
American: Man, Keith is such a moose fucker! I know cabin fever can get bad, but why doesn't he just polish off some alcohol instead?
Canadian: Well, he's originally from Georgia, so he only drinks Southern Comfort. But a Moose's bunghole offers just as much comfort!
