This is why I don't advise keeping fat chicks as pets. They tend to get irritable when you don't feed them. 

According to the video posted on YouTube:

OKC fan was waving a KD jersey in the air right before the 4th quarter when a drunk Spurs fan from a row behind us walked down and grabbed it, then threw it. OKC fans obviously was pissed so he walked up and punched Spurs fan. OKC's girlfriend got involved. Spurs fan hit OKC's girlfriend and choked her. Cops came. Meanwhile, another Spurs fan sucker punched OKC fan. OKC's girlfriend jumped on Spurs fan. Spurs fan No. 2's mom then whaled on OKC's girlfriend in the blue with Louis bag on her shoulder the whole time. Poor older lady next to sister, who I was trying to drag out of harms way, got trampled. So did my sister. Crazy. Whole place, including Thunders bench, was watching us the whole time.

Here's a different angle.
