Ratchet is the word best used to describe this video.  

A fight video surfaced online showing two women battling it out on the ground.  The girl on the bottom had a tight grip around her opponent's hair and was landing some heavy, unanswered punches racking up damage on her her rival's face.  This prompted a woman in a motorized wheelchair to ride up and jump in the melee in order to help her friend.  

Despite the fact that the lady had no legs and only one arm, she still got busy and put in work while trying to rescue her friend from a serious beatdown.  She crashed her wheelchair into the girl on the bottom and immediately began throwing punches down on her before falling forward out of her wheelchair and continuing her assault on the girl who was beating down her friend.

Check out the bizarre footage above.
