This is what a psychotic Baltimore Ravens fan looks like apparently. He nails the behavior pretty well, especially with the Joe Flacco jersey. The first video is when Ray Rice tied the playoff game against Denver in the 3rd quarter, the 2nd video is when Jacoby Jones ties the game, and the final video is after the Ravens hit the game-winning kick in double overtime.
Personally I think this was staged, but at the same time, the fact that the kid’s don’t react to the bizarre behavior at all means they have probably seen it before. Hopefully some friends of his see it so they can publicly shame him for this the next time they see him.
