What started as a spat between fans from opposing teams during Sunday's Detroit Lions home opener spawned a profanity-laden viral video of belligerent, apparently drunken Lions fans.

A YouTube video of the quarrel between the Lions fans at the game between Detroit and Minnesota is making the rounds online tonight.

"The two girls in front of us were drunk before the game started," the video's description reads. "They grabbed one of our signs and trashed it (real classy) because we're Vikings fans, and then spent most of the first half mocking us instead of watching the game because the Lions were ahead....."
