This is a song about "Knees in"

"what you doin'?" nothin' much, would shout some other stuff

You'd make a mess if shit was dangerous, on knees in cuffs,

Knees week, arms are sturdy

Trying to catch me riding dirty

Feed niggas shells like my motherfucking beach is nice

Bending those monster, making them grab their knees

Gettin weak all in my knees

I'm sharper than shark teeth

I'm screamin' out fuck the police

Nigga please ill have you on your knees

But in the meantime it's lights please

Spelling bees, scraping knees, losing keys

Test me, guaranteed you'll fall to your knees

Y'all be the next in the long line of war stories

I find peace in between her knees

Is it this black mercedes
