Has anyone tried learning another launguage

I am bilingual. I speak fluent Redneck, Missouri hillbilly, Ridgerunner, and some Flatlander, also speak Cajun (also known as CoonAss), some NE Yankee, and a little Wisconson, still working in Canute!! I also know most all the bad words in Spanish.
Having been raised in SW Ga, I speak most dialects related to Black folk. And I know what words to NOT use too. lol
