Oral [bad word] 
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 [bad word] up towards your mouth
Your pancreas excretes stale septic pus
Your whole digestive system is now a sticky mush

Rectal vomit in your thorax
Retch your anal tract

Liquidized oesophagus mixes with bloodied excretion
As you pathetically gasp for breath
The stench of hot faeces scorch your nose
As you violently vomit to death

Your intestines are rising, up towards your throat
Stale bile escaping through your bloodied nose
Your colon digested into acidic slush
Your tongue gargling on your dislocated [bad word]
