There are skiing competitions.
Professional skiers train to improve.
Athletes are paid money to ski.
These days people consider pretty much anything a sport, ie. Poker, Gaming, and even sometimes Snowboarding. As not to offend those who participate in their beloved sports, the same way Adolph's friend has offended some of you guys, I have learned to broaden my personal interpretation of sport to any activity that thrives on competition, rewards hard work, and relies on any sort of skill.
So if you and your work buddies want to train towards being the best burger makers this side of 4th street has ever seen, and then have a tournament at the end of the week, by all means, call it a sport. Just don't expect me to buy your crews season edit.
