MMA is a brutal sport to be apart of, whether it would be the intense fans and fighters, or what this article entails the biggest jerks. This list is filled with people who simply cross the line, with their attitudes and how they portray themselves to be.
Along with this list, are personalities who are very famous, and well known MMA fighters, some of whom you may not have thought would have made it on this list.
We all know MMA involves beating people up. In every sport, there are nice athletes who are beloved by fans, and in all sports, there are people full of themselves. People who couldn't care less about what you think, what the guy next to them thinks, or what their parents think. This is not to say fans don't enjoy "jerks" in MMA, as they fuel excitement for the sport.
15 Melvin Guillard
Melvin "The Young Assassin" Guillard is known to be one of the older jerks in MMA. After losing to Justin Gaethje, Melvin talked bad about his employees to the media, and about other people close to him. Guillard is a trash talker, notably about the World Series of Fighting, and Brandon Girtz.
14 James Toney
James Toney's jerkhood started right out of high school, as Toney had an offer to play college football at Michigan. He turned it down admitting to being a jerk, and that he would be unable to listen to anyone but himself. This attitude followed him into his boxing career with former boxer Jeremy Williams saying, "James Toney is the biggest jerk in boxing".
13 Cecil Peoples
"If you don't like me you can go to hell," is a phrase that is indicative of Cecil Peoples' career as a referee.
Many people hate Peoples for his overconfidence, and he has a reputation for being inconsistent. He once messed up as a referee for the Lyoto Machida vs. Mauricio Rua fight.
12 Michael Bisping
Michael Bisping is especially known for his trash talking. He incessantly talks trash to opponents, or people he doesn't like, and can be seen batting down cameras in public when people try to take a picture of him. There are many rumors of fights with fans he has been apart of. Aside from all of this, Bisping once spat on Jorge Rivera, which is the ultimate sign of disrespect.
11 Quinton Jackson
Quinton "Rampage" Jackson is one of the biggest jerks in entertainment, seriously, here's how.
In 2008 Jackson was involved in a hit and run, where he was not the victim. He hit a car with a pregnant woman in it, and she had a miscarriage; Jackson then fled from police at the time.
10 Josh Koscheck
Koscheck's personality is in question and has been for many years. He was kicked out of the U.S. Kickboxing Academy, and also told people he hoped that the facility would burn down. His peers aren't favorable of him either.
9 Nick Diaz
Dana White claims Nate Diaz NEVER answers any texts or calls from him, which you will know if you have ever been blown off, is a huge jerk move. Diaz is as unprofessional as it gets during pre-fight events. We can't forget the time he gave Frank Shamrock the middle finger during a press conference. He even fought Joe Riggs at a hospital once, over his anger from previous fights.
8 Anthony Johnson
Other than being noted as rude and even abusive to people in the gym, Anthony Johnson is a textbook jerk. Whether it be his rudeness or unprofessional attitude in the cage, Johnson is always up to something. His peers have nothing nice to say about him, mainly due to his alleged domestic abuse, as some claim, he is abusive to women.
7 Jason Miller
Jason "Mayhem" Miller has been arrested on many occasions and been charged with domestic violence. Miller promotes drugs among one thing he loves in his life, and he always shows his emotion, which is usually anger. At least he doesn't lie about his mean attitude, as he is very straight forward.
6 Tito Ortiz
Ortiz has never been liked by many in the MMA community, which is probably why he is nicknamed the "Bad Boy". He has angered many people, including, Dana White, Ken Shamrock and Chuck Liddell during his tenure in the UFC. Oritz once made rude remarks about Matt Hamill, claiming he had a soft head, due to his deafness, which caused quite a controversy from the deaf community.
5 Karo Parisyan
Karo is the absolute king of excuses in MMA, Diego Sanchez even called him out for it. His unprofessional attitude is noted by everyone who follows the sport. He is known as a mean guy, who simply doesn't like to interact with fans on any level. His title of "King of Excuses" is because he always drops out of fights before they occur.
4 Dana White
If the UFC is filled with jerks, then Dana White must be the president of jerks. Though he has contributed so much to the sport of Mixed Martial Arts, his attitude is noted by many to be arrogant and annoying. Fighters especially voice negative opinions about the guy, constantly questioning his motives. Dana himself talks bad about fighters intentionally, or "snitches" on them for certain actions, which gets them all in public trouble.
3 Ken Shamrock
When he was coaching The Ultimate Fighter, he did not take coaching seriously at all. He joked around and didn't really do his job properly, with many speculating that he just wanted to collect a paycheck. The legend even lashed out at UFC for unknown reasons, along with ESPN in 2016; many think this was for publicity. For a business that made him so much money, and basically made him, why would he be so arrogant to call them out like that?
2 Shinya Aoki
This Japanese fighter is viscous, in and out of the ring. It should be noted that Shinya Aoki broke a fighter's arm, and flipped him the middle finger in 2009. Here's what the Aoki had to say about the incident:
When I had his arm behind his back, I could feel it popping, I thought, ‘Well, this guy’s pride just won’t let him tap, will it?’ So without hesitation, I broke it. I heard it break, and I thought, ‘Ah, there, I just broke it.’ I was stopped afterward, but even if I hadn’t been, continuing to break it more would have been fine by me.
1 Conor McGregor
None other than Mr. Irish himself, Conor McGregor tops this list. McGregor prides himself on being a jerk, and frankly, that is how he makes cash. He's known to call out fighters on really anything, like at UFC's press conference UFC Go Big in Las Vegas. He hijacked the event and talked trash about almost every single member of the UFC for eight straight minutes.
