Please teach me about Dr. Dre's lyrics of "Let me ride".

"Let me ride" lyrics ↓

Creepin' down the back street on D's ("D's" refers to Dayton Rims)

I got my glock cocked cuz niggaz want these

Now soon as I said it, seems I got sweated

By some nigga with a tech 9 tryin' to take mine

ya wanna make noise, make noise

I make a phone call my niggaz comin' like the Gotti boys

bodies bein' found on Greenleaf

with their fuckin heads cut off, motherfucker i'm Dre

so listen to the play-by-play, day-by-day

rollin' in my '4 with 16 switches

And got sounds for the bitches, clockin' all the riches

Got the hollow points for the snitches

So would you just walk on by, cuz I'm too hard to lift

and no this ain't Aerosmith

It's the motherfuckin D-R-E, from the CPT

on a ryhmin' spree, a straight G

Hop back as i pop my top ya trip

I let the hollow points commence to POP POP POP

yeah, cuz if it don't stop

I have to put my shit in reverse go back and take anothers stop

Cause I'm (Rollin in my six-fo')

with all the niggaz sayin

First of all, I can't understand that meaning of "Creepin" and "Deez".

Creepin' is "Creeping" isn't it?

What means "Deez"?

Dr.Dre has a song which name is "Deeez Nuuuts".

I didn't understand meaning of the song name.

So I consult a dictionary before. But I didn't find the meaning.

So I used Yahoo serch of United States.

As a result, I could understand the meaning with great difficulty. lol(^^)

Maybe, the answer is no doubt.

If the answer is correct, nobody can not write here will.

Does "Deez" of "Let me ride" have a relationship to the answer?

Lastly, I can't understand "Greenleaf".

I can translate the word literally, but is this case meaning place name???

Please teach me to above.
