He's saying "awww" like isn't "aww, isn't that special.". That's how I read it.
The media, and some fans, seem to be ignoring the context of this altercation. The fan was having fun going back and forth with Denver fans in his section. Then the salty Nugget fans escalated everything by dumping a beer on him, while Suns fan still didn't throw a punch or try and climb up and fight. It wasn't until after dumping a beer on him and talking more trash to try and provoke him into a physical altercation that one of those Nugget fans decided to throw a total cheap shot and got owned for it. He deserved that and more but the Suns fan really kept his cool a lot longer than most people would have. Then he was applauded in Denver by Nugget fans in the area for finishing what those ****** started. So Richard Jefferson even suggesting that Booker giving the guy tickets was setting a bad precedent showed how little Jefferson knew of the whole incident to start with.
