If it's what i think it is, it's a game where people on two teams run around flinging a ball (that looks about the size of a baseball, but harder) between players using funny looking raquets. As i understand it it's played here (UK) by public school kids but overseas by complete nutters who consider it fair to aim at an opponent! The ball is supposed to hit some pretty high speeds at times.
I don't know the complexities, but it's basically ice hockey except that the 'puck' is a hard rubber ball (yes, about the size of a baseball), and the sticks aren't grounded, they're always in the air trying to catch and fling the ball.
Both of you are correct. Its a great game and I highly recommend it. I play defense, but Ive also tried Middie and Attack. They are all fun, but I like defense the best cuz all you do is knock the crap out of the attack and the occasional middies.
