a. A sex act so depraved that even Stephen Colbert can't put it into words. Allegedly involving moose antlers, a bottle of maple syrup, and the stanley cup, but it is also believed that the entire Toronto Maple Leafs team must be involved as well for it to be considered Canada's History.
b. A sex act performed during the coldest snows of winter during which the participants (usually 20 or more) light fires and dance naked and covered in maple syrup before... ugh, I just can't say it.
Dude... you pulled a Canada's History? That's fucked up, man... even for you.
