"Cole never flopped, nah" (J. Cole – Chris Tucker) | accepted

Another basketball reference.

A flop is to oversell contact in an attempt to draw a foul call. Usually away from the ball.

"Next time I'mma flip the script, you know, kick some shit..." (J. Cole – Chris Tucker) | accepted

A slight reference to Dr. J, who was essentially his whole team when he played.

"What the fuck you saying? All that aiming and miss" (Earl Sweatshirt – Molasses) | accepted

This could be shot at those who say Earl’s music is “word salad” rap. His detractors say he struggles to create a point or theme and often misses when he tries to.

"Email full of emails, I never write back" (Tyler The Creator – Nightmare) | accepted

Another Plain Pat reference, Tyler generally does not have producers other than himself and occasionally other OF members (Left Brain and Tyler produced Transylvania) produce his music.

"You're a shitty parent, face it, suck it up / That's what..." (Tyler The Creator – Nightmare) | rejected

Like Tyler, Thebe’s father walked out on him as a child. Holding true to Bastard, he says he’s not worthy of being Earl’s parent.

"Talking to me is like a fucking body missing its neck" (Tyler The Creator – Nightmare) | accepted

This adds on to the therapy line, he’s proclaiming himself a lost cause to them, saying that they’re wasting both his and their own time.

"Fuck math / Teachers should teach us to get Smith & Wesso..." (Joey BADA$$ – Hardknock) | pending

A large majority of gun sales are done by everyday people, not registered vendors. The circulation of these guns is out of the control of the government. Joey wants to see some of these guys out of that circulation.

"They told me "more dress-up" I'm giving too many lectures" (Joey BADA$$ – Hardknock) | rejected

Adding on to RaS' suggestion, this could also be an age reference. Joey, who is nearing 18, raps with the subject matter (and way of explaining it) of someone twice his age. Whoever “they” are, want Joey to be your typical under-20 rapper with generally less important subject matter (Diggy for example).

"Just got word from my mans on the island," (Joey BADA$$ – Hardknock) | accepted

This could also mean Staten Island. Staten Island is known for being indulged in mainstream culture, while BK is known for rappers and hipsters, that way of thinking. Joey’s friend from SI could be seeking life guidance.

"'Til the day I die, I'll be puffing lye, fuck the world, ..." (Joey BADA$$ – Suspect) | pending

Also, Lye is a strong base that corrodes and kills if ingested. What this line also says is that he’ll puff lye in defiance until he dies a “dry” (no wounds) death.
