I was watching the Williams/Stosur match when this incident happened. Williams hit a forehand and yelled right before it got to Stosur. The umpire awarded the point to Stosur, the tournament referee confirmed the ruling, and Mary Carillo expressed that Serena's yell was unsportsmanlike and bad form. Then the TNB began. Serena accused the umpire of being the same woman who "screwed her" two years ago when she was called for a foot-fault against Clijsters. (It was later confirmed that it was not the same umpire - but all Whites look the same, and all Whites are out to get Serena.) Serena kept talking **** to the umpire during the changeover, at the same time telling her "don't look at me", "your'e ugly, on the inside". Of course, when the match was over, Serena refused to shake the umpire's hand. It was a disgusting display of Negro perceived victimization, and of course the US Open crowd loudly supported Serena.
At least Serena admitted that the call had no bearing on the ultimate result of the match. However, she could not bring herself to admit any wrongdoing in berating an umpire who was merely doing her job. She told the umpire "you're an ugly person, on the inside"... but only proved that she herself is hideous, inside and out.
