The crawling heart reeks   Like fungus from the soul   The prowling worm seeks   Its grace and its grief      Heart is sworn   And the worm, it licks   Tongue like thorns   And the spit burns holes      Heartworm   Heartworm      The fever aches   Grows with the tainted self   The sweat flows   And paints the inner hell      Heart is sworn   And the worm, it licks   Tongue like thorns   Heart is sworn   And the worm, it licks   Tongue like thorns   The spit burns holes      The fever aches   Grows with the tainted self   The sweat flows   And paints the inner hell      Heart is sworn   And the worm, it licks   Tongue like thorns   Heart is sworn   And the worm, it licks   Tongue like thorns   The spit burns holes
