"Still whip work to the white yolk, absolutely!" (Kendrick Lamar – Cartoon & Cereal) | accepted

He’s not referring to cocaine.
Gunplay is exaggerating the idea of white brutality towards African Americans. As slave owners often used to whip their black slaves with a lash. He also drops a pun on the word whip. You can prepare eggs in a whipping fashion in such a way that you can make white yolk.

"Go to war with the Mormons," (Jay Z – Renegade) | accepted

How about including a general idea of what “the Mormons” are.
Mormons are people who practice Mormonism. Mormonism is a Religious and Cultural movement sparked in the 1820’s. They would emphasize standards they believe were taught by Christ. Mormons would look at shady with disgust. But he doesn’t care, he’d “go to war” with them.
Clever internal rhyme scheme as well
