The kings of trolling were back at it Monday night when 50 Cent & Conor McGregor decided to go at each other on Instagram again. It all started when Conor posted a picture of him and his new commercial ad with Burger King, while boasting about becoming one of the top paid athletes in the world this year and sending shade to Floyd Mayweather in the process.

“I am also really interested to see this years Forbes highest paid athletes list," Conor wrote. "I have now surpassed @cristiano Ronaldo as I told him I would in 2016. Floyd as a retired fighter that makes ZERO substantial revenue outside of them ropes is not on the list, and in the long game, is already dead. Mixed Martial Arts is a glorious game, Floyd. You are going to love it hahaha Someone tag 50cent in this for me. He blocked me on this the mad 50 year old instagram blocker. Ahh don't block me 50 kid, I still like some of your songs. The older ones hahah."

Well after calling him a “mad 50 year old Instagram blocker,” 50 Cent caught wind of the jab that Conor sent and decided to of course retaliate with a response of his own. Sharing a picture of a short Irish leprechaun, 50 wrote, “What you say little man? I’m a tell Floyd to kick your ass up and down the street. LOL.”

This minor exchange is just the latest in 50 & Conor’s on-going feud over the past few years. 50 cent said he could take Conor in a street fight, while Conor has continued to call 50 a “bitch” among other things.
