bowel howl 

A Fart: A fart of specific audiophonic quality, a long melancholy sound with a gradual drop in tone identical to the howl of a wolf

It was a still moonlit night, my last meal contained raw onions, the dusty old house lay silent. Out of respect for partner I lay on my side pulled back the duvet, letting out
a spectacular 'bowel howl' the likes of which would inspire a novel by Sir Arthur Conan Doyle.

Irritable Bowel Howl 

A low pitched howling noise someone with IBS makes when they are feeling some kind of discomfort, often emotional. It can also be used to accentuate a sentence with little to no effect. The noise can be be best described as the sound that a dinosaur would make when hit by a train.

Jack: Nice Irritable Bowel Howl, there.
