Ok, let's go with this explanation, probably you are right.
I don't think it's by any stretch a feasible prospect...
1. It's a slang for "doesn't/don't have".PS.Sorry, I have two questions about your sentence.
1.In what way “ain’t got” is different from “doesn't have” here?
2. Why do you use the double negation structure in the sentence (“ain’t” and “no”)?
2. Because it's kind of a set expression "ain't got no/nothing".
3. I should probably avoid using this sort of redneck language, but I use it sometimes just for kicks.![]()
