The informant is describing a piece of folklore from within the quidditch community. Quidditch is an increasingly popular sport among college students. It was originally based on the fictional sport from the harry potter novels adapted to exist without magic. The sport has now taken on a life of its own, having an official governing body in the International Quidditch Association. There is even an annual Wold Cup for the sport. This particular piece is about one of the people who runs the organization.
So, I heard about Will Hack’s broom at the World Cup V in New York. And it was during the MSU UCLA game and, where we saw Will Hack illegally, uh, doing a lot of things illegally. And… he made a girl cry! And tackled her illegally, and was being a douchebag. The whole west had a chant going that said “Will Hack’s Broom.” And this is not a new thing. Apparently, the whole United States Quidditch League knows about it. So, and then after UCLA lost to Middlebury, a bunch of USC kids, we just what? reenacted his thing across the pitch. It was fun. Basically, instead of holding his broom upright between his legs like normally you’re supposed to do… upright? sideways? I don’t know. Normally! He has the broom dragging on the floor. Where he, it almost, he almost has it coming out of his legs. So it’s almost illegal. So I feel like it’s an ineffective way of playing quidditch. Especially since he’s one of the people who wrote the rulebook.
This has spawned many pieces of folklore that go with it. There is the gesture of dragging a broom which instantly identifies someone as a member of the quidditch community. There is also the chant which unifies someone as a member of the western region.
