Floyd Mayweather and Conor McGregor had some choice words for each other during a press conference at Brooklyn Barclays Center ahead of their fight in Las Vegas.

Both contenders treated fans that waited hours for the latest stop in a promotional tour to about 30 minutes of profanities, crude cracks about body parts, and a steady stream of even more f-bombs.

McGregor, who turns 29 on Friday, was the picture of cool as he walked the red carpet inside Barclays Center.

The UFC star wore floral pants, sunglasses and ditched a shirt for a polar bear mink coat he bought earlier in the day in a Fifth Avenue shopping spree.

Undefeated boxer Mayweather taunted Mcgregor fans, playing the enemy as he shrouded himself in the Irish flag.

Mayweather even made it rain at one point, throwing dollar bills into the air over McGregor.

McGregor held up one of the bills and laughed as he pointed out to the audience that it was indeed only a dollar. 

The presser was an effort to hype up the biggest fight in recent memory when the two will go toe-to-toe on Aug. 26, at the T-Mobile Arena in Las Vegas.
