A lot of parallels to the previous line:
It wasn’t uncommon for the winning army of warriors and barbarians to rape the women after killing and conquering another tribe or town.

Even though Redman tells us that he’s not that type of person, he confirms that he is. The line word is bond which is frequently used in hip-hop basically equates to someone giving their word that what they are saying is true.

Warrior and barbarian refer to the times when the world was considered relatively uncivilized. The culture was often about killing to resolve conflicts, even if small, as opposed to the culture now where conflicts are attempted to be resolved by diplomacy and, if necessary, “civilized warfare”.

This line is admitting that he’s not some brute with a blood-lust, even though some of his acts seem to imply that he is.

Using gangsta to describe his roots, his name (Baby Gangsta), and what he raps about; he’s saying Lil Wayne will corroborate his story because that’s who he entered the rap game with as a teenager (in The B.G.‘z)

Redman references his previous appearance on EPMD’s “Hardcore” from their 1990 album Business As Usual. Red also included his verse from “Hardcore” on his debut album.

Redman drops a reference to R&B group Guy’s 1988 track “Teddy’s Jam.” Red also referenced the track on “Watch Yo Nuggets” from his debut album.

A reference to the movie Goodfellas in which Joe Pesci starred.

Erick Sermon is providing some free advertisement for the music retailer Sam Goody, a store that sold cassette tapes at this time since they were still popular with Walkman users. The company filed for bankruptcy in 2006.

In early hip hop, rappers made it a point to distinguish themselves from R&B singers, since the latter were considered soft due to the nature of their songs, whereas rappers typically came from rough backgrounds.

400 years is roughly how long the USA and the territories that came before it have enslaved or discriminated against people of African descent.
In the beginning blacks were killed often due to slavery, then later due to discrimination/hate-crime, and at the time of NWA, gang/street violence

Tribute to the deceased DJ Screw and the incarcerated Pimp C, both contributed heavily to the Houston rap scene.
