They mean Popeyes "brought back" nuggets -- they had them around 1986-87 or so. At least at the location near Transcontinental and West Esplanade in Metairie. That was the one location that Al Copeland himself still owned, so maybe they tried stuff out at that location.
They had them at other locations. It was my go-to as a kid when the family got Popeyes, since I wasn't a big fan of bone-in chicken. Those nuggets with their sweet and sour dipping sauce was the bomb.
