seems to me mostly its just good natured fun, bustin chops is just how blokes talk to each otherSome of these guys just have fun busting people's balls. It's either a sport, or a hobby, not sure which. Haha.
Probably have to ask my ex, I'm pretty sure she holds the patent and all intellectual property rights on the name ball-busting, If it was to become a sport she couldn't compete at an Olympic level though, being a professional and allYep. That's why it might be considered a 'sport'. Since all sports have to do with balls, we could call it ball-busting or something.
