Conor McGregor had some mercilessly harsh words to say about “fat mess” Ricardo Lamas

Conor McGregor let loose with his trash-talking acumen during the UFC Boston post-fight presser

This time, it was top featherweight contender Ricardo Lamas who felt the full force of McGregor's acerbic tongue. Lamas, who fought and lost a unanimous decision to champion Jose Aldo at UFC 169 last year, released a parody video at the expense of the Irish MMA superstar last week. Production values aside, the video was all pretty tame , at least in comparison to some of McGregor's finest trash-talking. However, the video genuinely seemed to annoy McGregor.

I swear I can't even get over that video. It's the most ridiculous thing I've ever seen in my life.

Fresh from pulverising Dennis Siver into submission in the main event in Boston, McGregor let rip at Lamas to the media.

I looked down into the crowd and I seen 40 chins. I climbed up them 40 chins and it was Ricardo Lamas. so, I gave him the finger as well. I seen him in the hotel with a big box of  pizza. Now I'm talking about a 22 inch pizza and on top of the 22 inch pizza was a big can of Pepsi or Coke. He's a big fat mess making stupid videos. Get in the gym and perform impressively and climb up that ladder. You fought like a pussy when you fought Jose. So, eh... he's a pussy.
