Never sniff that blanco, that's word to OJ's Bronco

from Action Bronson – Larry Csonka Lyrics on Rap Genius

Meaning

Bronson stays away from cocaine (a.k.a. the white pony a.k.a. Colombian Marching Powder). “Blanco” is the Spanish word for white. He also shouts out O.J. Simpson’s famous white Bronco (a bronco is essentially a pony), notorious for its role in the low-speed car chase that preceded O.J.’s arrest for double murder.
