UFC fighter Leslie Smith beats man who groped her friend: 'I just dropped elbows on him'

Just some friendly advice for ... well, for everyone on the planet: Don't be a scumbag.

And if basic human decency isn't enough to dissuade you from being a scumbag, please remember that victim of your wretched scumbaggery could very well be a trained martial artist who makes a living punching people in the face.

Case in point: UFC women's bantamweight fighter Leslie Smith.

Smith and a group of friends (including fellow fighter Heather Jo Clark) were about to enter The Mint - a karaoke bar in San Francisco - when a man walked passed them and grabbed Smith's friend's butt.

Big mistake.

"I followed him and I was like, 'Hey, you can't do that,'" Smith told MMAFighting.com's Marc Raimondi. "And he was like, 'I can do whatever I want.' And I was like, 'No, you can't.' Then he turned around and spit on me and threw a big right hand."

Bigger mistake.

The punch didn't connect, and the man, completely unaware that he was about to grapple with a professional fighter who trains with the likes of Nick Diaz and Gilbert Melendez, grabbed Smith's hair.

"He had my hair, so I pushed him against a building and then I double-legged him," Smith said. "I took him down against the cage and then I started to take his back, but his hair was really gross and it didn't quite feel right."

Smith made the transition from the man's back to mount and started raining down elbows.

"I let go of that and just dropped elbows on him," Smith said. "He turned over and I just dropped elbows on him from mount against the building until he started saying, 'I'm sorry.' Then I stopped as soon as he said sorry, because that was really the only thing I went over there for."

Nicknamed "The Peacemaker," Smith doesn't condone violence outside the cage and is only publicly telling the story because she knows women are victimized all the time.

"It has given my friend and all of my female friends so much pleasure to know that happened," Smith said. "It's not an unusual thing for a woman, a good-looking woman in public to get grabbed and fondled by strangers. At first, I was trying to keep the whole thing on the down low and not say anything about it, but after seeing how happy it has made so many women, I changed my mind."
