What you doin in L.A., with Filipinos and ese's
Latinos and Chevys, down by Pico with Frederico

from Jay Z – Intro: A Million And One Questions/Rhyme No More Lyrics on Rap Genius

Meaning

Most of LA’s population are Mexicans and Phillipinos, well that might have been the case in 1999

Mexicans are known to be the main drug suppliers…Jay knows this…so he’s saying that people question his affiliation with Latinos, which is obviously drug related.
