There’s the sound of contempt on the other end of the phone. Or is it chaos mixed with a strong dose of bedlam?

Maybe it’s just anger.

Lots of it.

Whatever it is, it’s speaking loudly in Spanish, and you don’t need a translator to figure out what the message is: Joel “El Cepillo” Casamayor doesn’t like Diego “Chico” Corrales. And he’s doing his best James Toney impersonation to make sure that’s both understood and heard by everyone around a phone.

Casamayor is not quite up to Toney’s high standards of conference call calamity yet, but it’ll work for now.

Still, his tirade could be just another sales pitch for their WBC lightweight title fight set for Oct. 7 at Mandalay Bay Resort in Las Vegas (SHOWTIME).

You know, “hate” sells. “Real hate” packs the house.

This will be the third time these two will have legally mixed it up, and heading into the fight, the score is dead even at one win each.

Both are expecting to win the three-fight series.

But right now, on another one of those interesting conference calls, Casamayor (33-3-1, 21 KOs) is spewing while Corrales (40-3, 33 KOs), the defending champion, quietly tries to answer questions.

Asked how he feels about Casamayor, who he’s never invited to dinner, Corrales just kind of shrugs it off.

“He doesn’t like me and he doesn’t have to,” Corrales says. “He‘ll never make me or break me. We don’t have to like each other to go to work. He can never like me and I won’t lose a wink of sleep over it.”

We’re pretty sure Casamayor doesn’t like him.

“I don’t plan on Diego seeing the 12th round,” Casamayor says through a translator. “That chin is touched.”

As in fine china.

It seems as though Casamayor is a little confused. He doesn’t understand why Corrales doesn’t like him when Corrales doesn’t even know him. And that sort of ticks him off.

“He talks a lot of garbage,” Casamayor says. “He talks about me and says I’m not a good person and he doesn’t even know me. That’s why on Oct. 7, I’m going to break his head. I’m going to put his mouthpiece through his mouth again like we did at Mandalay Bay. He’s lost every October fight he’s fought, and he’s going to lose another one.”

Close. Corrales has lost three fights, two of them in October.

Still, Casamayor is on a roll. It’s his chance to vent, maybe take a few verbal swings at the injustices he believes have been delivered by Diego.

“He talks a lot of sh– and garbage about me and my family and he doesn’t know me,” Casamayor says. “If he had a conversation with me, he knows me and I’d understand. But I don’t talk about him and his family.”

Asked if he’d been talking about Casamayor’s family, Corrales didn’t get a chance to answer.

It was still Casamayor’s ball, or at least he thought so.

“He can talk all the sh– he wants, but we’ll settle it Oct. 7. If he wants to fight in the street, we can do that too.”

“Hmmm,” Corrales wisely says. “That’s what you don’t want to do.”

There’s not a lot of money in street fights.

While Casamayor makes the accusations, Corrales claims he’s innocent of all charges. Or at least most of them.

“If I’m going to say something bad about someone, I’ll say it to his face,” Corrales says. “But I never bring anybody’s family into it. That’s just not me.”

So, did Corrales ever call Casamayor a – gasp – bad person?

“Yeah, I said he was a bad person,” Corrales admits. “I don’t like him. We don’t have a good relationship and we never have.”

But I bet Casamayor makes weight.
