I'm coke boy leanin' on you niggas
If money talk then I must be screamin' on you niggas
from Pusha T (Ft. French Montana) – Doesn't Matter Lyrics on Rap Genius
Before he was a rapper, Pusha was a big time cocaine dealer, hence the nickname — coke boy. This is another shot at Lil Wayne.
Leanin' is used as a homophone;
A reference to Waynes prison stint at Rikers Island in 2010. He was addicted to lean before he went in — a combination of cough syrup and sprite.
Once he was out, many said he lost his ability to come up with the same lyrical punchlines that made him famous. His probation prohibits him from taking any drugs. The homophone is completed because Wayne used to lean on the lean, aka “depend on it” to make him a good emcee.
Thus, both drugs of choice have been established for the two rappers, Pusha then goes onto use a nice play on talk/scream. He’s saying with all the money he has — instead of talking, he must be screaming.

Coke Boyz is also the name of French Montana’s crew:
