I guess one could call it “chain referencing”. A rapper makes wordplay around one thing throughout multiple lines instead of the usual one line like we’re used to. Three examples I’m sure this site would be familiar with:

Drake - Tuscan Leather
Aye, b, I got your CD, you get an e for effort
I piece letters together and get to talking reckless

Drake - Jodeci Freestyle
All this capital it's like I left the caps lock on
It's like every time I plot a return I seem to shift the game
See I can still talk keys without pitchin' cane

And then of course…
Kendrick Lamar’s verse, Pusha T - Nosetalgia

The way Mickey Factz employed "checking boxes" at the end of "wraith" was insane

Yeah this is hard

Niggas'll lose they mind for it
Wine for it, dine for it (pussy)
Spend time for it, see no colored line for it (pussy)
Double back handicap and go blind for it (pussy)
P**** got endless prisoners
P**** always revengin' her
P**** is calculating
And good p**** is rather dangerous
P**** can be so facetious, the heavyweight champ
P**** is so undefeated, let's amen to that
I mean, the pump fakes on the Facebooks
And the screw face when the bae look
Won't get you no p****
I mean, the fake chains and the gold names
For insecure, gon' reassure you not to get p****
You overcompensate too much for the p****
You like to throw all kinda shade for the p****
See, that's what p**** niggas do
I know the ways of a p****, I see p**** lookin' at you
How many niggas get mistaken for c***oris in a day?
How many sentiments you make before runnin' p**** away?
How many times she gotta tell you that d*** is disposable?
But if she f*** a young nigga like me, it's over for you
Solána, middle fingers up, speak your truth

Does a song like Lupe’s Gotta Eat count? those type of songs that stick to the same wordplay topic for the whole song, I like them

Ask God for an answer, it's crickets
I guess he didn't make us in his image
Are we real boys or mimics?
I can't lie, I just keep tryna spin it
I guess I'm a cynic
But why ain't Geppeto mind his business?

Quantum physics could never show you the world I was in
When I was ten, back when nine ounces had got you ten
And nine times out of ten, niggas don't pay attention
And when it's tension in the air, nines come with extensions

Nas 100% has songs like this

Earl on 2010

When the mood change, i'ma poker face em,
It's a new day, who got all the aces?
Who be folding late, who know when to play dead?
Who sit up straight when the roof caved in?
Had a full plate, you aint wanna split it,
Tell it to you straight, you ain't wanna listen

Earl on East with the card wordplay again

My soul and my heart, all in it
Keep fishing, God, the macabre finish
That missed my pop dukes might just hit me
Depending where i play my cards, the wind whisper to me

That Kendrick one is nice

Lupe on Precious Things about hand gestures

Shoutout to the 6ix, R.I.P to 8
Swear this s*** is gettin' ate, I'm on ten for the cake
Get a lot of love from twelve, but I don't reciprocate
Fifty-one division stay patrollin' when it's late
21 my addy, so the knife is on the gate

Sins, I got sins on my mind
And some M's, got a lot of M's on my mind
And my friends, yeah, I keep my friends on my mind
I'm in love, I'm in love with two girls at one time
And they tens, that's why I got ten on my mind

Resort to cantankerous means on the cash play, rat races
The cheese sit in the trap, wait
It snap, then we break
Somethin' reachin' for me from the waist

The opposite of punch line bars

He's too good

Extended metaphor vs simile

Big Benjamins like the Pittsburgh Steelers
Drake, you got it
Robert Kraft sent the jet for us, that s*** was patriotic
You would think we live in Baltimore, the way they ravin' 'bout the latest product

Did it before -Weezy

/end thread

I got my head in the clouds, I'm serious/cirrus
The lyrics begin to reveal themselves over time periods
Promise you'll get that s*** when the sky clears

But now they gotta pay that s*** direct to me
I send the label bills, bills, bills like the other two women standing next to Bey, that s*** was just—

Independent - women is loving the new appearance

Matter of time before I go net a B/Bey like apiarist

Ever since me and Dre split it 50/50 on 50, it's funny

We got a buzz spreading quicker than making paper airplanes out of a 20

F*** money, I don't rap for dead presidents

I'd rather see the president dead

It's never been said but I set precedents (said presidents)
And the standards, and they can't stand it

Sidebar, Serena, your husband a groupie
He claim we don't got a problem but
No, boo, it is like you comin' for sushi
We might pop up on 'em at will like Suzuki
Kawasaki, sushi, saké, the money grow on trees like shiitake
They tried to get spicy with me, so I wonder how they gon' stop me
I'm really on a roll like hamachi
The f*** would y'all really do without me?
For your birthday, your man got a table at Hibachi
