"I ain't owe nobody nothing!"
It seems to me that what they might be saying was: "I don't owe any debts whatsoever." But then why make it sound so confusing?
I want to discuss, regardless of what the speaker intended to mean... What is the true meaning (according to the rules of English and logic) of the phrase: "I ain't owe nobody nothing."?
Please discuss the true meaning of the phrase from your point of view. You may say, "who cares what the True meaning is when they want it to mean X ("I don't owe any debts whatsoever"). But see it matters. Because I can't just go out there and scream "I bought 3 apples" and then upon being reminded of this, simply shrug and say... "I REALLY said, according to my own language, I bought 4 pears and no god damn apples." See there should be rules of logic and English at least to some extent and its collective to a degree.
So to rephrase the discussion point:
What, according to you, is the true meaning (using rules of English and logic or a combination thereof) of the phrase: "I ain't owe nobody nothing."?
