Actually, we're not sure she's cheering at all. If a team's performance warrants a noise like this from the audience, they're probably not in it to win it. In it to summon massive hellbeasts from the bowels of the earth, maybe. In it to gather tithes for Cthulhu, sure. But beating someone in a friendly game of handball? This is leagues beyond that.
We hope this woman's team won—or rather, we hope we never have to hear the sound she makes when they lose.
