The only thing mightier than Tito Ortiz's ground and pound is his mouth.
On the receiving end of his latest verbal volley is, not surprisingly, his upcoming opponent, Rashad Evans.
But Evans says this time, the notorious trash-talker may have crossed the line.
Taking a page out of the Don Imus how-to-get-fired-in-a-heartbeat playbook, Ortiz wrote in an underground web forum that the African-American Evans "will be my nappy headed ho."
"He crosses the line and those comments are offensive," Evans said.
Ortiz said he meant nothing personal by the remark - though Imus, a CBS radio legend, was recently fired for throwing the exact same term at a U.S. college basketball team.
"It was just a joke to get a laugh out of my fans," said Ortiz, whose UFC record is 16-5.
Evans said the joke will be lost on throngs of blacks who will feel insulted.
"Even if you're saying it in a joking around manner, a lot of people don't joke like that," said Evans, who is undefeated at 15-0 in his UFC career but will face his most formidable challenge in Ortiz in Sacramento tomorrow.
"It makes him look like a clown. My uncle called me and he said 'You gotta whoop that boy's ass. You gotta whoop his ass for all the years of slavery.' It rubs some people wrong."
Evans took a couple of shots of his own at Ortiz, saying he thought he lost his fight against Forrest Griffin last year despite the judges giving him the decision.
Overall, said Evans, Ortiz isn't the fighter he once was.
"He's just distracted in a lot of areas. Once you start reading your own press clippings, that's the end of anybody."
The pair will be one of the feature fights at UFC 73: Stacked in California.
