Damn it, Jets fans. You couldn't just be happy with a beautiful New York afternoon, the NFL's Opening Day, and a 20-point win over the Bills. You had to punch a (possible) chick in the face in MetLife's Section 302.
According to this video's description, a group of Buffalo Bills supporters in the nosebleeds spent Sunday's game being heckled by Jets fans, and as they were leaving, this fight broke out.
I've studied this clip like the Zapruder film now, and here's what goes down: A large person in the No. 85 David Nelson jersey, who has pigtails and I assume is a female, is seen arguing with the guy in a black tank top. Her (boy?)friend in the No. 95 jersey comes over to defend her, and he and "Ronnie" in the blank tank start to go at it.
The girl lingers around, though, and the guido absolutely decks her at the 35-second mark. To the rest of the Jets' fans credit, they chant "Asshole" at him before security finally comes around.
