Letras: Carcass. Reek Of Putrefaction. Excreted Alive.

Eaten alive
Munched into pulp
Premature necropsy
Comes closer with each gulp

Brain not fully dead
Decrepit splattered libs
Mass ensanguined spasms
Excretion now begins...

...Semi-conscious human faeces
...Semi-digested squirming pieces
...Semi-animate in excrement
...Semi-terminal constipation
