There was no need for anything else, but he let his emotions get the best of him and taunted a bloodied man he'd already physically beaten, then badmouthed a major sponsor of his company and finally, flipped off the fans.
Soon after pulling off that trifecta and the heat of the moment wore off, he realized he'd gone too far. And for the record, he apologized.
Lesnar explained that coming from the entertainment business of WWE, hyping fights was part of his ordinary mindset, and it's the only part of his past job that remains.
"I have nothing against Frank," he continued. "The only thing I have against him is that he beat me. In the end, this stuff comes out because I'm just amped up."
Just to make sure Lesnar got the point, UFC president Dana White walked back into the champion's locker room shortly after his match, pulled him aside into the bathroom and let him know his conduct wasn't acceptable.
"Any fighter will tell you, you get emotional out there at times," White said. "You say stupid things you don't mean. What he did was so far over the top, I can't even describe it and put it into words ... He apologized like a real man would. He said, 'I'm embarrassed.' "
The win took some of the luster off Lesnar's otherwise dominant win over Frank Mir. Evening the score from their first go-round, Lesnar was able to stay out of Mir's submission traps until finding an opening that led to a series of hammer-like right hands that ended the fight. According to White, Lesnar could possibly next see the winner of the upcoming Shane Carwin-Cain Velasquez UFC 104 matchup.
