UFC superstar Conor McGregor isn’t backing down from the big bad wolf. The MMA fighter has ripped 50 Cent in a new, must-read social media post.

Conor went to Instagram Thursday (March 8) with a savage rant-filled caption on a throwback 50 pic.

Earlier in the week, 50 Cent poked fun at McGregor and said money went to his head.

“They love ’em some McGregor. They get their haircut like McGregor all that sh*t. As soon as they get that first big check they gonna leave their motherf*cking wife and kids like McGregor and sh*t.”

A few nights ago, 50 threw some hard-hitting jabs at the MMA fighter.

“Listen, if you don’t like my humor, just stay the f*ck off my Instagram. I don’t give a f*ck about what you’re talking about. Motherf*cker on there talking about I ain’t culture. I’m hip-hop culture. You understand me? I’m hip-hop culture people. … Don’t get me f*cked up. Conor McGregor is a talented fighter and all that. He’s talented for a white boy. But you know n*ggas have superior genes when it comes to that kind of sh*t. White people, in order for white people to have a champion they had to make Rocky, man. They had to make that sh*t because they can’t actually do that sh*t. It’s just too much work. They’re like, ‘What the f*ck?’ How that n*gga work so hard?'”

This week, Conor took direct aim at 50’s longtime pal Floyd Mayweather Jr.
