Executive summary: Some doofus is sooo disgusted with Michigan football that he's going to burn all of his Michigan gear and switch his loyalty to another team, which he's picked via the time honored method of an eBay auction (the proceeds of which he's giving to the Red Cross). His new team is - wait for it - Ole Miss. Yes, Michigan football is so bad and so embarrassing nowadays that henceforth he will root for college football powerhouse Ole Miss.
The accompanying video features the doofus reading a renouncement of his Michigan loyalty while wearing an Ole Miss sweatshirt. Then his small pile of Michigan gear of Michigan gear is shown ablaze to some incredibly overwrought music. Assuming that the whole thing isn't meant to be ironic (and, try as I might, I cannot detect a single whiff of irony here), I have to give thanks that this guy is no longer a Michigan fan because, well, dang.
