Monkey see, monkey do, shorty sipping sunny dew
Monkey see monkey do is an expression describing someone who imitates another person’s actions, good or bad, simply by having watched them before. So he could be saying that that kid imitates the old by sipping Sunny D to be cool.
It could also be that other rappers imitates Nas, something he attacked Jay Z on “Last Real Nigga Alive” for instance.
Now the progression in the next line turns into hard liquor. Note the consonance on the letter M and S: Money — Monkey, Shorty — Sipping — Sunny. Making some cool internal rhymes.
