Funk Flex gets his pettiness on.
Funk Flex has been in the game for a minute and has seen a hell of a lot in the game. So there's no doubt that he felt Diddy's sentiments of hip hop being oversaturated. However, Diddy didn't say it in a malicious manner but in a way to explain his fear of hip hop becoming diluted. Diddy's help bring up some of the biggest artists that have shifted hip hop in a major way and Funk Flex has watched hip hop blossom from its inception to where it is now. Diddy's latest comments must've inspired Flex because he aired out his list of "wack rappers."
Flex's inclusion of Lil Pump and Lil Yachty doesn't come across as shocking by any means. He's definitely from a generation that doesn't really understand or appreciate the music either artist makes. However, listing Nicki Minaj seems a bit more personal. Flex and Nicki's issues with each other stems back to 2012 after she and the rest of Young Money were no shows to Summer Jam. He's also previously claimed that Nicki and Drake don't write their own lyrics either.
G-Eazy on the other hand might just be based off his own personal opinion. There's never been any noted beef between either of them in the past.
