I'm too tough, gettin snuffed all in the cut
Aiyyo it's diggedy Das whassup higgedy here to fuck it up
Nuttin move but the green my team be on the shine
Shiggedy shine like a light, Hit Squad we keep it tight
I light an L I ring your bells so go tell cuz it's the ill figure
Timberland boots, Rolex, with a Benz
Diggy Das EFX snap necks with PMD
Bringin the raw so you can see a b-boy is what I be
See I just can't resist this, cause Business is Business
So money mind your business, and shorty keep your distance
I did this once before, hardcore, forever in it
Tryin to win it, thank God for hip-hop, yo Scratch spin it

Yippie-yi-yay, yippy-yo, it's the, slow-flow mechanic
Mass confusion is crusin just start to panic
and you don't stop, got the Hit Squad backin me
Aiyyo we riggeddy rock your set
and I bet you never ever tackle me
What happened P?
You know what happened B I'm on mission and
lost my other half but I still got my Fisherman
hat, it ain't over til the fat chickenhead catch
wreck
Aiyyo yo it's diggedy Das EFX
The sewer rap so iggedy act like you know though
And me the Mic Doc (c'mon) the micraphone's my only
friend, can't even trust nobody
It goes liggedy-la-di-da-di
Higgedy hit you with the shotty
So to whom it may concern, from yours truly, no other
My style's butter, that's word to mother, underground gutter
B-boy brother, no singin chords, just rugged
Low budget, thought you was that nigga but you wasn't
Riggedy rough rugged and raw, straight from the floor
Fearless like the Four, Zsa Zsa like Gabor
Babe-Pah, we zonin up the hydro Squad by my side so
All my real heads keep it live represent

he wants some Das Efx (only the hardcore will get THAT reference)

Yo!
Get the fuck off my dick and let me rip this shit!

I write raps,
And when niggaz bite, I clap,
'Cos their shit sounds better now.
You done let me down,
I thought it would be dope, but instead,
Your shit's dead,
You gets fed
To the alligators lurking in the moat,
Peep what I wrote,
You bit so hard, I though your shit was a quote.
But still I'm taxing, axing the competition,
And any wack men, I stomp & dis 'em
Easily.
And you can feel the pressure, plus
When I bust MCs'll be
Trampling eachother trying to exit,
When I flex it,
The way I wreck shit is not unexpected.
Niggaz just lose when I choose
The best crews of MCs,
And turn 'em into refugees.
I slaughter a lotta MCs that are the
?Styles I compiles?, and cut 'em up like ?vows?.
Think to yourself I write the shit
So you can bite the shit,
And I'll know, despite you get props.
[To da beat!]
Niggaz get dropped.

Sample: That's how it was and that's how it is!

Enough with this wackness,
Enough is my ?check?,
Enough with these motherfuckers biting DAS EFX.
I come real when I show skill,
(Hey, yo, Saafir!) You macked on that ho ill,
And that's for real, my flow still
Is everlasting, niggaz forever blasting
Shots when cash gets hot.
You're not fresh, so you hating when I be just
Ripping microphones without stating the obvious.
Now how much harder can it get?
Niggaz try to flow, but they soundin' like me
A year ago.
Shit, old, kaput, I got loot,
To the hos I'm cute, and so I always got boots.
It's me, so be free to feel the ?Ivy swing?,
More niggaz got my back than Rodney King.
I feel tight, knowing that the shit I write
Will be exposed to foes, and everyone will feel fright.
And you'll run and tell your man, "Yo, peep this twist,
It's real, try to practise." But the mack is
Way ahead of ya, instead of ya wack sound,
I'm kickin' shit to make MCs back down.
Got rhymes that kills, fills many empty heads,
Niggaz can be dead, I got 'em in line, like ?Stimpy?.
Red light, slow that shit down, bring it to a halt.
You're wack and it's all your fault
