Yonkes is an informal (slang) Spanish word used for junk and/or junk-yards. Yonkes does NOT refer to "Yankees" as some monolingual English people erroneously assume. This word is iconic at Chicano Park in Barrio Logan, San Diego, CA thanks to a civil-rights-era mural that reads "Varrio Si, Yonkes No." Meaning "yes to community, no to junk-yards." This was in response to the City of San Diego's decision to zone junk-yards in a heavily Mexican community during the 1960's.
Spanish: Vamos a los yonkes a comprar unas partes para mi carro.
English: Let's go to the junk-yards to buy some parts for my car.
A person who likes to take drugs, mainly heroin. They look all fucked upp.
Me: WTF! Get out of my backyard! Fucking Yonkie!
Yonkie: I am not a yonkie! *Sniff* I just like the feeling of empty syringe.
Me: Yeah right! And what's that? I'm gonna tell you, that's HEROIN, FUCKING YONKIE!
