Hola: I have a question for the young and/or street wise native Spanish speakers out there. I was watching Scarface recently, one of my favorites, and I wondered where the slang term "llello" comes from. It's a slang term used in the movie by the Cuban and Caribbean narcotics traffickers to refer to cocaine. I don't know if I'm spelling it correctly. The phonetic spelling in English would be "yA-yO" where the a and o vowels are long. Any help is appreciated. Thanks.
