A video of a teenager giving an impassioned performance on the field with her marching band is going viral due to just how impassioned said performance is. It's maybe the most impassioned marching band performance ever, in the history of marching bands, including possibly John Philip Sousa himself. If you were to look up impassioned in a dictionary, you would see gifs of this girl's face (if you have some weird gif dictionary, anyway). She performs with utter abandon, and the internet is loving it—the video has been viewed well over a million times on Facebook since being posted on July 10.
