is a term the Spanish-speaking community uses to define those women who think it is cute to wear "BABYGIRL" or "SEXY MAMI" on blouses and sport drawn on Sharpie eyebrows ; a ghetto Latina who thinks huaraches count as formal attire ; it is a term used to demean a woman who you may think appears to be less sophisticated than you.
OH-EM-GEE Stacy, look at that naca.
Does she like, not own a mirror or something?
You can totally tell the sequins on her blouse were SO glued on.

Omgosh, look away before she like, totally throws a "chancla" at us.

Hey naca, why did you burn los frijoles? Now we don't have anything to eat.

"Partially derived from the word "knocker", and almost acts as a possible subsitution for "nigger" but takes on a unique meaning that can only be understood by a "naca" himself

1. a real good buddy, or friend, who never lets you down.
2. a member of a tight group of friends that play it cool, and always know how to make things interesting." -Vile Scamp

In Addition:
A naca will always share weed with another naca, no matter how low their stash.
My naca, thank you for the great bud.
