Hey! I play lacrosse, and I know it's not as popular as other sports, so not many people know about it.
So, for CyanSliver and everyone else, here is a
Wikipedia.
In short, lacrosse is played on a field a bit larger than a football field. You use a stick with a net at the top to hold a ball that is about 3 in in diameter. You can pass, dodge, whatever to get to the other teams goal, and then you'll shoot. I'm not good at explaining, the wiki is better at that. But lacrosse is played a lot like basketball, since basketball was invented by lacrosse players, and its also played like hockey, a tiny bit of soccer.
