[Verse 1]
This ain't Sinatra!
This ain't the Carter!
I am the chaperone nigga...Who brought ya!
I am the author! This is Holy water!
From the Holy Father...The Rock of Gibraltar!
Step up to the altar! Step up to the slaughter!
Get circumsize son and turned into a daughter!
Niggas know they oughta drink the fucking Kool-Aid!
Industry laid out authorities are too late!
MC's passed the due date! Niggas? They do hate!
You are Bobby Boucher, I'm the Mane like Gucci!
I rock the Louis! But not like Kanye!
Nigga see me kinda like...Harry Belafonte!
Step into the room they be like: "Ah, Day-O!"
Yeah, cause they know a nigga ain't play-doe!
Shots all fatal! Is this Laredo?
Boarder town knock them down just like Lego's!

[Bridge]
Drink the Kool-Aid!
I make a motherfucker drink the kool aid!

[Hook]
(Let them know!) Do you (Let them know!) Do you

[Verse 2]
I ain't the Doctor! This ain't the patient!
This ain't that nigga always on vacation!
This ain't no white boy's rehabilitation!
This is crazier than a boat full of Haitians!
This is inflation mixed with degradation!
This ain't no dead rappers reincarnation!
I heard it was a New West Coast, I ain't worried!
I murder more stars than Conrad Murray!
I got more bars than the penitentiary!
I wrote this shit without a rhyme dictionary!
Young bucks try to step up to the harim!
Looking for some pussy I'm an old buck, I dare them!

[Hook]
(Let them know!) Do you (Let them know!) Do you
(Let them know!) Know who you fucking with? Know who you fucking with?
Do you (Let them know!) Do you

Ice Cube

Straight outta South Central Los Angeles, Ice Cube became one of the most respected rappers in hip-hop, helping to usher in the era of gangsta rap with N.W.A and as a solo artist. He has gone on to become a mogul in Hollywood but still remains true to the game that brought him his success.

Born O'Shea Jackson on June 15, 1969, Ice Cube got his name from his older brother, who threatened to put him in a freezer and pull him out when he was an ice cube. He began rapping in high school and started his rap career as a member of Stereo Crew, which released the single “She’s a Skag” through Epic Records in 1986, and C.I.A. with the 1987 track “My Posse.” Both groups featured producer Sir Jinx, the cousin of DJ/producer Dr. Dre.

Ice Cube’s big break came when he wrote the song “Boyz n the Hood” for Eazy-E, which led to the formation of N.W.A. as a group. After the release of the 1987 compilation N.W.A. and the Posse, the group released their classic debut Straight Outta Compton in 1988. A financial dispute caused Cube to leave the group in 1989 and start his successful solo career, starting with his 1990 platinum debut Amerikkka’s Most Wanted.
