victoria luz said:The words seem to be creole corruption of Gambian words (iko for ago, un day for amay, etc). Very broadly speaking, they mean: Hey hey! (or Pay attention!) I/we are listening!
Joc-a-mo-fee-no-ah-nah-nay means Don't mess with us! We are for real!
They are verses in Cajun, from the traditional chants sung in New Orleans for Mardi Gras Indian parade (sfilata di Carnevale delle tribù in costume tradizionale).
