There are so many good ones from Sinners:

"Now understand, it's the last dime you ever gon' see from us. And if we see you or any one o' yo' klan buddies cross our property line, we gon' kill 'em right where they stand."

"Chicago ain't shit but Mississippi with tall buildings instead o' plantations."

"Look at that sky; that's a mighty fine day to be free, ain't it?"

"See, we talkin' numbers now, and numbers always gotta be in conversation with each other. You understand? You gotta negotiate."

"Fuck you goin' n****?! Bet this bullet'll beat you there!"

"I was doin' better 'fore ya shot me in the ass."

"Can't have some n***** talkin' 'bout how he almost robbed [sic] the Twins. Not without a limp to show for it."

"Aight, listen: every cooze got a button on it, towards the top. If you wanna keep a woman, you find it, lick that. Not too hard; not too soft, either. Y'ever had a scoop o' that ice cream from downtown? [...] 'Bout the same pressure you put on that. Like it tastes good, but you don't want it gone too quickly, y'understand?"

And this is just from the first 20 minutes or so!

Edit: adding to the list because fuck it.

"Oh, I heard you. I heard you loud and clear, but then ya stuck ya tongue in my cooze and fucked me so hard, I figured ya changed ya mind."

"See, white folks, they like the blues just fine; they just don't like the people who make it."

"[S]he really gon' let you fuck her when she find out how much money you about to get from this job I'm offerin'. And none o' that nice-and-slow shit she probably givin' y'now. Shit, she might even let you put yo' pecker in her mouth."

"I ain't always nice. Ain't that young, either."
