"@Real_JustRebel: So @LupeFiasco what u think about Kendrick verse on big Sean's control track?"
I liked it

Meek Mill had this to say about it

“It definitely wasn’t insulting. It was like me playing Dion one-on-one in basketball. I’d tell you ‘Dion, I’m going to slam on you. I’m going to cross you over, I’m going to give you 30 points today, “Kendrick Lamar, I don’t think he was trying to insult any of us, you know. We all know each other personally.”

Joell Ortiz went in on Kendrick Lamar claim to be the King of New York, on his song "Outta Control" saying

“Lil homie you ain’t the King Of New York/You the next thing on my fork…Maybe that’s why you left me out of that shit/Maybe that’s why the Slaughterhouse ain’t get dissed or maybe I’m not on your radar,” Ortiz raps.

BIG K.R.I.T in an interview with HipHopDX talked about the being mentioned by Kendrick Lamar

“Rap, Hip Hop has always been mad competitive,” K.R.I.T. said Tuesday. “It's exciting because it was probably crazier for his fans, for him to mention my name among rappers that people would consider top tier, [rappers] people kind of look at as being the future and my name just randomly popped up. So what I got an opportunity to see a little bit last night and this morning, was just people that probably never tweeted me before, whether it be negative or positive. For me, it was like, ‘Thank you for the promotion.’"
“It let people know that, ‘Yeah, I'm from the South and yeah, I'm country but you ain’t going to take me lightly," K.R.I.T. said. "Aint none of these rappers going to take me lightly on a record.’ And [Kendrick Lamar] know that. So that's why my name ended up on that list. If you think about ‘1 Train,’ or any record, I’ma give my all. People know that I'm a lyricist and I can compete with some of the best and it is what is. I appreciate the shout out because that’s really what it is. It’s a competitive sport; it’s a gladiator sport. Don't nobody want to get murdered on a record. That just it is what is. So I don’t know, brother. I was like, ‘Hell yeah.’ It is what it is. Thank you for the shout out and shout out to all the fans that he may have that didn't know about my music and now they gon’ go back and listen to records and check out ‘1 Train,’ and want to know why he felt the need to mention my name. And I’m 100% sure he probably gets tired of going to barbershops and hearing my name mentioned where he is and vice-versa. It's all good man. It's all within the sport.”

@kendricklamar it’s okay to be cocky and sure, but we all need somebody to lean on. Let’s just call it mentoring."Can't argue with zen.
