People who dismiss sport as "just a bunch of grown men chasing a ball around". Fair enough if you don't like sports but there's no need to be a condescending douchebag. I could just as easily dismiss movies, tv shows and theatre as a bunch of people playing make believe.
You tend not to see it so much in NZ where most folk "get" sport. I've never understood that attitude though as playing sport even at amateur levels requires at the very least commitment. When I did the enduro bike ride the training was crazy and gave me a real appreciation of what professional athletes put themselves through.
