(plural borborygmi) Noun:a rumbling or gurgling sound caused by the movement of gas in the intestines.
My comment: my next Dark Lord in my next book shall certainly be called Balthrog the Borborygmus.
I am so totally kidding. My next Dark Lord is actually named Enmeduranki Nimrod-nipu Shitimgal Duhumunamaru, He Who Binds Earth to Heaven, Son of the Mighty Hunter, Architect of the Tower of Darkness Absolute.
Borborgymus is the name of his Dark Land. It is beneath the shadow of Mount Eructation.
