It's not known why exactly the fight started, but there's not a lot of reasons for a guy to deck a female in the face the way this Jets fan does here. According to a Deadspin source, a fight between two women started in the MetLife Stadium stands in which beer and clothing were thrown. Apparently it spilled into just outside of the stadium, which led to this ugly display of force. The woman did charge after him in this video, but there's hardly any defending the guy's action when you hear the smack of his fist connecting to the woman's face. A bad look for Jets fans.
