An extreme sport. This is possibly the most hardcore sport on the planet. Its is known mostly to the country of Switzerland and their hardcore olympic gold medalist team. Canadians suck at this sport, naturally, because they suck at everything. It is also very popular sport in the state of New Jersey. This sport was pioneered by a kid named bill. No body knows his lat name.
