"And my nigga big Suge, known for keepin shit poppin" (DJ Quik – Dollaz + Sense) | rejected

Quik is Piru and Suge had his own ties to Blood gangs. “What’s Poppin?” is a common greeting for Blood gang members.

"Yeah you left out the G cause the G ain't in you" (DJ Quik – Dollaz + Sense) | pending

When he performed this at Source Awards in 95, Eiht’s people got enraged when this particular line was spoken.

"So whether or not you understand, that there's only one D..." (DJ Quik – Dollaz + Sense) | rejected

no no no……in gang dialect, a letter attached to “K” normally means “K” stands for Killa or Killed. This is used in graffiti tags. “CK” would stand for crip killa. However it is not customary to keep such annotations as a nickname and only for the tags ergo Blake drops the C completely out of his name which as BigRob noted out would normally be marked over with an “X”

"Buck one, buck two, buck three, buck fo'" (Bow Wow – Bow Wow (That's My Name)) | pending

this seems like an interpolation of American Football quarterback cadence: “Hut One, Hut Two, Hut Hut Hike”. Combined with a sample from Whodini’s “Freaks Come Out at Night”.

"Five mics in The Source, ain't holdin' my fuckin' breath ..." (Eminem – Say What U Say) | pending

also “Dont Hold Your Breath” is an idiom for people who have false hope on situations unlikely to occur. Normally people take bis gasps and hold their breath in anticipation of surprise. Em knows there is no point in any sense to want Five Mics in the Source no matter how many people tried to denounce him for not having that achievement.

"Little hit of Dre's weed, I can do anything / Catch a con..." (Eminem – Say What U Say) | pending

no no no, because Dre can’t write/rap for himself. This is definitely about Dre supplying Em good California marijuana.

"White 'Pac" (Eminem – Say What U Say) | pending

“I Just Don’t Give A Fuck” on 2Pacalypse Now. Eminem had covered or sampled this song a few times on his earlier Slim Shady albums

"Cause I know if they get up I won't get a chance to let off" (Eminem – Say What U Say) | pending

The phrase: “Keep you foot on his neck” applies here. When you have a person in submission do not grant him or her a second chance by “not snapping their neck” as they can get up and kill you. Eminem is looking to murder his foes as fast as possible.

"And swing to knock somebody's fucking head off" (Eminem – Say What U Say) | pending

I think Em actually means(in a figurative sense) he wants to knock the guys head off.

"And I'mma only sucker-punch and swing without warnin'" (Eminem – Say What U Say) | pending

Eminem and Dre are speaking out their rapping personas at this point in their lives. Dr. Dre preferred to be more laid back and tranquil while Eminem is more provoking and outlandish with his demeanor tightroping on near psychotic behavior. Em being the “Devil’s Advocate” is going to “shoot first, ask questions later” when it comes to conflict.
