At the UFC 196 press conference, featherweight champion Conor McGregor trash talked Nate Diaz, who incidentally gave as good as he got.

I honestly like Nick’s little brother, said McGregor. How can you not like him? He’s like a little Cholo from the hood. But at the same time, he coaches kid’s jiu-jitsu on a Sunday morning and goes on bike rides with the elderly. He makes gang signs with the right hand and balloon animals with the left hand.

McGregor’s barbs did not sit well with one unfortunate fan.

McGregor had previously been investigated in his native Ireland over an image of the fighter with what appeared to be an automatic weapon. It ended up being a toy. However, the weird, weird fan took that as a starting point, and in a potentially threatening way, noted that while that was a fake long gun in Ireland, there are real ones in Murica.

Who knew?

“Be careful bout talking down on neighborhoods,” wrote the weird fan. U dont run s**** here except UFC & the hood uses guns not fists this aint ireland.”

A fan then responded with a jibe.

“I’m sure he s****ing haha. FFS,” he wrote.

The weird fan then got weirder.

“not sayin he should be but this aint ireland we got guns here & plenty of crazy ppl,” he wrote.

The post was accompanied by an image, presumably of the weird fan, holding what appears to be an AK-47.

Zombie Prophet, who is one of the most under appreciated figures in the MMA space, brought the tweets to the UFC’s attention.

The UFC immediately brought their security team in, who in turn contacted McGregor’s security, Twitter (who removed the offender’s account), and the FBI, who are investigating.
