NSFW: Listen to What Conor McGregor Says to Chad Mendes After Knocking Him out

Conor McGregor is many things. 

"Reserved" is not one of them. 

After finishing Chad Mendes at UFC 189 Saturday in Las Vegas, McGregor shared a moment with his foe inside the cage, opening up a bit and baring his true feelings. 

For all the trash-talking leading up to this fight, it's clear McGregor has respect for one man. It's also clear his feud with another man, one UFC featherweight champion Jose Aldo, is genuine. 

Grab a set of headphones and listen carefully in the video above from YouTube user TvMaLsv British. Pay close attention from eight seconds to 16 seconds in the video. 

Did you catch it? 

If not, don't worry. The detectives at Reddit.com's MMA subreddit, /r/MMA, already transcribed this one. Here's what they think McGregor says: 

"You're a legend for taking this fight....He's a juice-head p---y." 

The respect for Mendes is cool to see. McGregor talks so much that we sometimes forget there's a good dude underneath the surface, and his budding camaraderie with Mendes revealed a different side of the trash-talking Irishman. 

But just a few seconds after praising Mendes for stepping up to the plate, McGregor talked about some "juice-head p---y."

Who, oh who, could that be referencing? 

It's obvious McGregor would be referring to Aldo, the 145-pound champion who pulled out of his scheduled showdown at UFC 189 just two weeks before the fight with a rib injury. UFC President Dana White insists Aldo's rib was not broken, and McGregor undoubtedly buys into that narrative as well. 

That would explain the "p---y" part.

A little drug test fiasco leading up to July 11, then, would explain the "juice-head" part. 

While Aldo's tests eventually came back clean, it's clear McGregor has lost all respect (if he ever had any) for the featherweight king. 

This just makes their eventual showdown—which may take place Jan. 2 in Las Vegas, per UFC CEO Lorenzo Fertitta (h/t ESPN's Brett Okamoto)—all the more intriguing.
