My LA experience saw a conversion of the word "Buey", meaning Ox, to Wey, meaning asshole when you wanted it to, or "dude" when you wanted it to. I would like to hear more about the use of buey as an insult.
"Esta pinche buey (this fucking cow)" used by a 5th grade boy to insult a sizeable 5th grade girl.
Oye, wey. Pasame el libro. (Hey, buddy, pass me the book).
