Floyd Mayweather Jr., who has steadfastly refused to answer questions about the most recent round of failed negotiations for a fight with Manny Pacquiao, has unleashed a profanity-filled racist and homophobic Internet rant against the Filipino star.

In an approximately 10-minute Ustream video, apparently made Thursday and also posted on YouTube, Mayweather repeated his assertion that Pacquiao uses performance-enhancing drugs, an accusation that resulted in a defamation lawsuit from Pacquiao earlier this year.

Mayweather, apparently in his home with a handful of members of his entourage in the background, ripped into Pacquiao repeatedly during the video.

"I'm on vacation for about a year, about a year," Mayweather said. "As soon as we come off vacation, we're going to cook that little yellow chump. We ain't worried about that. So they ain't gotta worry about me fighting the midget. Once I kick the midget ass, I don't want you all to jump on my d---. So you all better get on the bandwagon now. ... Once I stomp the midget, I'll make that mother f----- make me a sushi roll and cook me some rice."

Mayweather's publicist, in Mexico for another fighter's promotion, has seen the video but has been unable to reach Mayweather or adviser Leonard Ellerbe. Kelly Swanson said she would not comment further.

Attempts by ESPN.com to reach Ellerbe were also unsuccessful.

Pacquiao dismissed the video, choosing to instead focus on his upcoming fight with Antonio Margarito on Nov. 13 at Cowboys Stadium near Dallas.

"I just heard about that, but I didn't see the video," Pacquiao said Friday, at the final stop of a three-city tour to promote his fight. "But it's an uneducated message."

When asked about the possibility of a Mayweather bout Friday, Pacquiao responded: "I'm not looking for that fight. I'm satisfied with what I've done in boxing already."

In the video, Mayweather at times spoke directly to the camera and at other times kept the recording running while he made calls to fans who had posted messages to his UStream and Twitter pages.

The tirade came as Pacquiao promotes his fight against Margarito -- a bout taking place only because Mayweather refused to fight him.

But Mayweather sure made it sound as though a fight with Pacquiao, one many believe will shatter revenue records in boxing history, will eventually happen. They have already had two rounds of negotiations fail -- in January and again during the spring.
