Carcass

Oral eruption
Rectal extroversion...
Your vagus implodes, as nausea strikes
Savaging your body in terminal retch
Violent spasms and decaying enzymes
Engulf your throat as you belch
Intestinal disturbance, your ileum turns inside-out
Your duodenum is thrust up towards your mouth
Your pancreas excretes stale septic pus
Your whole digestive system is now a sticky mush
Rectal vomit in your thorax
