Faecal Encephalopathy 

If you wind up in the emergency room because, say, you were trying to launch bottle rockets out of your anus, you can expect to hear this term thrown around. Latin, or pseudo-latin, is often used to convey unflattering terms and make it sound grandiloquent to the uninformed (or faecal-encephalopathic) ear.

Variations include Cranio-Rectal Syndrome and Cranial Rectosis, presumably for when the patient has shit for brains
