Take your pick from several renditions of the 1969 hit by Tony Joe White. Polk salad, properly spelled "poke," is American pokeweed, a poisonous plant that needs to be boiled, rinsed, then boiled again before sautéing it in a skillet with bacon fat. A "poke" is a small bag or sack. Sock a little polk salad to me. Chomp, chomp, chomp.
