Ravens Fans Chant 'Bullshit' During Game Against Patriots (VIDEO)

The players and coaches aren't the only ones fed up with the NFL's replacement referees.

Ravens fans expressed their disapproval with a profane chant for the ages on Sunday. The crowd at M&T Bank Stadium finally lost it when a series of calls went against their team in the fourth quarter. First, a dubious illegal contact penalty negated a Baltimore interception. Shortly after the play, Ravens coach John Harbaugh was flagged for unsportsmanlike conduct, prompting the fans to start vigorously and loudly chanting "Bull-shit!"

Harbaugh claimed that he had been hollering at the official in order to call a timeout, but perhaps the referees interpreted it as excessive arguing. Either way, the flag was thrown. And then the chant began.

"That's the loudest manure chant I've ever heard," NBC announcer Al Michaels said.

The Ravens fans' anger turned into joy at the end of the game as kicker Justin Tucker barely made a 27-yard game-winning field goal at the last second.
