Double negatives affirming one another instead of negating is a common thing in language, known as “emphatic negation” or “negative concord”. Middle English used emphatic negation and various English dialects still use it to this day including African-American English. They’re saying exactly what they mean, just not in Standard English. Just like they’re probably not pronouncing the words the same way. No reason to get annoyed.
Reminds me how annoying it is when English speakers use “ain’t no” in a sentence.
Which is just a double negative that practically almost always means the opposite of what they mean.
