Canibus has some good ones but this is my fave:

Now if a bitch sucks yo' dick, for five dollars per square inch 
And gets forty dollars, includin' a five dollar tip 
How big was the dick she just sucked? 
(Say what?) 
Say how big was the dick she just sucked? 
(What?)

I overheard my mother singing some song and a line about "getting more ass than a toilet seat"

I don't know what it's from but that is an immaculate lyric.

Step up in this motherfucker just a-swingin' my hair.

“I used to drive a dinger with the dents in, now it’s pearlescent, and the bonnet got the vents in.” - (Bonnet = hood of a car)

"Luda, Jada and Nas // and our bullets give you a deep tissue massage // so here's a song and dance while I make these ends // you never stood half a chance like Siamese Twins."

I was raised in the city...shitty..ever since i was an iddy biddy kiddy drinking liquor out my mama's tiddy.

Mom’s spaghetti

Like watching 1000 lemmings plummet just because the first one slipped

Swagger tighter then a yeast infection
Fly go hard like geese erection
Fashion patrol police detection
I stay tight like Chinese connection

Dr. Carter by Lil Wayne

Real Gs move in silence like lasagna.

I'll rip a tree out the ground and flip it upside down 'Fore I turn over a new leaf, clown

Maybe I am the ballot in the box / the bullet in the gun / the inner glow that lets you know to call your brother son and really that whole theme song.

Honey, check it out you got me mesmerized

With your black hair and fat-ass thighs

I only wish I could find someone someday who will think of such romantic things to say to me...

I'm a pimp by blood, not relation,
y'all still chase on, I'll replace on

If you don't recognize that truth and the one who spat it, gtfo this thread you poser ;)

And, perhaps, this lesser known

I rip rappers and take responsibility,
For makin' future hall of famers look third-rate,
Y'all are lost for words like,
Conversation on your worst first-date,
And raw beats creep through side streets,
Loose leaf notepads, that's where rhymes leak,
Punch-lines, man, don't even beg,
I got knee-slapping tracks, y'all cruisin' ya leg,
You a rhyme-writer, buddy? Man, that's a joke,
You ain't worthy of being my secretary,
Man, that's a quote

If you do recognize that, well, you're just as fucking goofy as me, which ain't much, but it's better than nothing. But it's a pretty fucking tight set of lyrics.

I like my sugar with coffee and cream.

I smell a grape in the duck preserves

m tryin' to explain, baby the best way I can
I melt in your mouth girl, not in your hands

Amazing reference game

"England is my city"

or

"Thats an awfully hot coffee pot"

One of my favorites from Oh Bo by Bo Burnham:
Pull it out, stick it in your mouth, and I bust in the back of ya
Swallow bitch, there's people starving in Africa

I made the change from a common thief

To up close and personal with Robin Leach

And I'm far from cheap, I smoke skunk with my peeps all day Spread love, it's the Brooklyn way

Down for the count, get up and dismount

'Cause I'm coming with an endless amount

Of rhymes in a hurry like a flurry

A collage to camouflage the power punch, but don't worry

Knowledge is an antidote, I got hands of smoke

Writing at the speed of light with insight I wrote

Rhymes at a level, so you can't relate

Unless you're intelligent, so stay awake

Used to speak the King's En-ga-lish

But caught a rash on my lips, so now my chat just like dis
