Reeking Septic Mass

Reeking septic mass
Chunks of ordure
A scent most foul
Springs violent convulsions

There exists
A mass of shit
Fecal entity
Flies will feast
On the mess
Disgusting lunch of rot
Mass of dung
Digested flesh
Orb of feculence
Reeks eternal
A stench of shit
From bowels of disgust

Horrid miasma
Digestion of decay
Foul excrement
A mound of revulsion
