I've played this game - it's oodles of fun but quite ridiculous at the same time. PE teachers and youth club leaders are all over like a free whore before payday, so I'd expect it will be around as a 'sport' for some time. Nah, it ain't a sport ...
Naw, it's mostly played on a sort of dusty bit of spare ground. It would be much more explosive and funnier if they played it on C4, though.
