I've always called them coyotes. I've pronounced it with a "long O and/or E" on the end. Just like Ole Webster has in the dictionary.
I have heard, Poor grammer to some is a sign of ignorance. Using profanity because you can't find a better word, etc... Well, that's what my english teachers used to tell us many years ago.
As far as "city speak", good grief come to one of our innercity schools and listen to what REAL city people talk like. I doesn't sound like the english I was taught. More like Rap.
