These lines are a distortion of Jay’s opening lines in Dead Presidents II The beat also sounds quite similar to the original Dead Presidents.

Who wanna bet us that we don’t touch lettuce
Stack cheddars forever, live treacherous, all the et ceteras
To the death of us me and my confidants, we shine
You feel the ambiance, y'all niggas just rhyme

In the movie Juice, the main character Bishop – played by 2Pac – shoots and kills a man then yells “Riverside motherfucker!”

Jay has traveled all around selling crack. To spazz means to go crazy so he is saying that he was wildly selling like there was no tomorrow (he could never be sure). This is also a simile on spasm as in an involuntary muscle contraction, a common symptom of a “bad back”.

This collaboration is bigger than just sales and fame, it’s about two of the greatest black artists in music at the time coming together to stand for the newfound prevalence of blacks in the music business.

Jay was facing someone in the exact same position as him. “Under his clothes” he may have been carrying a weapon, used to procure these items for his family, drugs for sale, or the actual items. “Cut from the same cloth” means they’re of the same background, or of the same mindset.

Jay had the drop on this kid, so he shot him. And he was caught, now living a life behind bars for the life he chose.

And it’s nobody’s fault I made the decisions I made
This is the life I chose, or rather, the life that chose me

It also echoes another song recorded around this time, “Ballad for the Fallen Soldier,” a track that equates hustling with a young soldier going to war. This is presented as a cautionary tale: Learn from the mistakes of these two kids.

Jay said something similar in “Lucky Me,” in which he said he’d rather take jail time than lose his life. Here, he’s justifying murder by claiming self defense.

As Jay has pointed out before “He who hesitates is lost.”

Also note the continuation of the cards reference using the word draw. Just like the previous line, this may be a metaphor for Jay taking his own path and overcoming the streets as opposed to the inverse.

Comstock is a hamlet in Fort Ann, New York that contains two prisons – Great Meadow Correctional Facility and Washington Correctional Facility. To sell wight you gotta lock down the block like Comstock locks down prisoners.
