A fight in a dressing room or lociker room, possibly the dancers dressing room in a club.  The girls watching the fight decide to let the two fighters go at it til they finish, but sadly the person taping it got distracted, so you only get to see about a minute of what looks to be a hot emotionally intense fight.  At about 1:34, you get a glimpse of what appears to me to be one girl biting the other's face.  I'm not absolutely sure that's the case but it looks like it to me.

It may very well have, it was so chaotic, and poorly shot, it's really difficult to tell.  It certainly wouldn't be the first time the women watching got caught up in the excitement of the moment.
