This line completes Nas’s chronology of the cars he progressed from owning.
Now Nas claims to be rolling in the dough, driving a Rolls Royce Ghost:

And Phantom:

These are two of the most expensive and luxurious luxury vehicles one could own.
Considering the fact that both of these cars are usually symbolic of lavish wealth and richness, and the fact that Nas professes to own both of them, it shows an extreme weath, a willingness to spend on style, and a carelessness with money that is usually seen as a admirable quality in the rap game.

Super Cat is a Jamacian DJ who features on this track, and Nas makes a shout out to him

Nas also references Super Cat’s nickname, Don Dada, which links him to the title of the song, as they both contain ‘Don.’

The nickname comes from contemporary usage of the phrase Don Dadda, which generally means someone who is in charge, most likely stemming from the roots ‘Don’ meaning a higher-up member of the mafia, and ‘Dada,’ a bastardization of ‘Dad,’ another mafia term for someone high up, like a godfather.

This is also a reference to Supercat’s track Don Dada.

Nas is no stranger to Latina girls. In this line, mentions that the girl is from Colombia, a South American country that was home to notorious drug lord Pablo Escobar, from whom Nas took his “Nas Escobar” alias

Colombiana is also the title of a recent film about a female assassin

Nas uses a couple of business terms to reiterate a common rap boast.

• The first is ‘Gross,’ which refers to ‘Gross Profit.’ Gross profit is the amount of money a business takes in, subtracted from the costs and losses that the business incurs. Nas uses this to refer to the profit he makes on all the music he has sold and is still selling to this day.
• The second is ‘Net,’ which refers to ‘Net Worth.’ Net worth is a term used to describe the most common measure of wealth. It is measured by taking all of one’s assets and money and subtracting all of their debts, ending with an accurate representation of their wealth. Nas applies this by using it to insinuate that he does, in fact, have a net worth, which is a term usually only used to apply to the rich or to businesses, insinuating he has a LOT of money.

Together, he says that whenever he earns money, he’s actually earning as much as his net worth, so his net worth is doubling every time he earns something.

This line is actually a fairly dense wordplay:

• First, it reference’s the children’s show Spongebob Squarepants, in which one of the characters is named Patrick Star, and is literally a STAR:

• Second, it references Shwayze’s recent pop hit Buzzin':

• Third, it references the often-intoxicated (BUZZED) deceased actor and celebrity (STAR) Patrick Swayze:

KY Jelly is a common sexual lubricant.

Unlike KY, which is known to be very slippery, Thewz alleges to never slip up in his music, which means that he claims to be very reliable and consistent.
This is a very rare thing in the rap game, as even the best of artists have almost infallibly faltered from time to time…
