Korean MMA star finishes opponent in seconds with brutal KO after disrespectful incident

A South Korean MMA star brutally knocked out his opponent within minutes of the fight starting after he was the subject of several bizarre taunts in the build-up.

Hyuk Min Ji quickly went on the attack against his Brazilian opponent Felipe Pereira during their fight at the BnD Black Cup event, which was taking place in Buncheon, South Korea.

Ji managed to wrestle Pereira to the ground inside the second minute of the fight, and rained down punches at his helpless opponent's head.

At first, the referee was seemingly hesitant to stop the fight, but did eventually intervene to stop Ji from inflicting any further damage and declared him as the winner.

Pereira had targeted his opponent with some brutal trash-talking in the fight build-up, which arguably went a step too far.

He brought a rubber chicken to the pre-fight press conference, before squeezing it repeatedly in front of his microphone. The rubber chicken is a popular novelty item across parts of Asia, particularly in Japan.

Pereira would later pull out a water pistol and fired it directly at his opponent, before threatening to fire it at a man in a suit who had walked across to intervene.

Once the pair faced off, Pereira pointed at his opponent and threatened him: "I kill you. I kill you."

That apparent confidence quickly dissipated once the fight got underway, as Ji made light work of him.

The punches unloaded on Pereira seemed to have some additional force behind them, given the Brazilian's pre-fight antics.

Pereira attempted to get up immediately after the knockout, though the referee tried to get him to stay on the canvas to receive medical attention.

One of the nastiest cases of “f*ck around and find out” just went down in Korean MMA

While he was on the ground, Ji mimicked a water pistol shot at his opponent.

Once he did get back to his feet, he stumbled towards the side of the cage and had to grip onto the metal to stop him from falling to the ground again.

Ji might have gone in for round two, having looked as if he would charge back towards Pereira, but he was stopped by the officials before his hand was raised.

"Ref wasn't letting him have that twentieth free headshot," one fan wrote.

"Lmao he was still p***ed even after he beat the guy's a**," another said.

And a third stated: "Wait this is better than American MMA."
