"I'm still kind of in the Olympic moment. I love the Olympics. I was just so proud of the final tally of gold medals that I contributed to. It was really awesome."
The dance Williams did was apparently based on the Crip Walk, a hip-hop dance made famous by Crip gang members in Compton, in the 1970s. And she didn't like that being brought up.
"First of all, it was just a dance," Williams said.
"I didn't know that's what it was called. Second, why are you asking me that? Like that's so — I mean, if anything you should be trying to ask me questions to lift me up, not bring up such things. I'm done with that question."
Williams was also asked about Kim Clijsters' claim that Serena is the best women's player of all time.
"I never think about that," she said. "I can't sit here and say I'm the best ever. I'm not. I'm not worthy of that title. I'm just Serena.
"I love playing tennis and I'm good at it. Just because I'm good at it doesn't make me the best."
