Exquisite Eschatology

Suctioning out the faecal detritus
Absorbing coproemetic grumes
Picking up excremental samples
Bear the fetor of rectal fumes

Fragments of alimentary matter
Contained in the yellowish sludge
Survivors of digestive process
Devoured by intestinal grubs

Qualmish faecal feast
Excrement, xysma and rotted offals
Haemorrhage from the eroded rectal wall
Grume, grume
Grume, grume
