Now I can't guarantee that this is a Michigan fan...but here is the video's description (posted the night of the loss to TSIW):
"#2 USC LOSES TO UNRANKED UCLA 13-9 AND MISSES OUT ON CHAMPIONSHIP GAME. MICHIGAN SLIPS BACK IN AND WILL PLAY OHIO STATE AGAIN FOR THE TITLE. YA BABY! GO BLUE!!"
Either it's a Michigan fan - which would be pretty funny considering they got jumped in the polls - or it's a Bruin fan - which would just make a lot more sense.
