[ ooc: I'm going to tweak this explanation so it makes the slightest ounce of sense in the real world and doesn't involve balls being knocked out of people. ]

oh, it's a kind of sport. you fight with these bats that have foam covering on them so nobody gets really hurt. the object is to hit your opponent and keep them from hitting you.

every time you strike them, they lose points. they can gain them back if they hit you the same number of times. so you have to make sure you always hit them more and dodge or block as much as you can. whoever has the most points remaining when the time runs out, wins. you can also win by taking all the other guy's points first.
