In blues language, sexual acts and organs are referred to through common metaphors. Kitchen images are especially prevalent; frequently the kitchen represents the woman's body. Jesus's complaint ("I can't hang around white man's kitchen") becomes richer in that context. Voodoo also appears in blues lyrics, just as it does in the story. Nancy's discovery of the hog bone, a curse and also a phallic symbol, terrifies her. It implies "that Nancy's 'curse' is her promiscuity."
