Noun (Kuh-thoo-loo-Ree-uh)

When either severe seasonal allergies, or a virulent sinus infection causes you to digest copious amounts of mucus through post nasal drip, the impending explosive intestinal distress will result in a bowel movement consisting of mucousy tendrils of hot fecal napalm which will feel as though the Old God is using your sphincter as a portal into this world.
Fred: Wow, the old Gods sure took out their fury on the toilet

Sean: No, that was my Cthulhurrhea, sorry.
