What qualifies as a "sport", and what disqualifies a "sport"?

[DynamiteRave]

I am a firm believer in anything which could cause any injury (something that would fall between a career ending injury and a hamstring pull) is a sport.

Competitive eating is not a sport (I've heard people say it is)

I do believe cheerleading is a sport though. One of my friends in the past was a cheerleader and broke her leg once doing it. Healed it up and went right back to doing it again. To me, that's definitely a sport.

I think bull riding is a sport too.. I enjoy watching it, that's for sure.
