Ok, so this probably isn't one you're going to be able to casually drop into a convo.
This word reminds me of the porky pie I used to tell my parents when I was a sugar fiend of a child. When they said I couldn't have dessert because I hadn't eaten my dinner, I'd calmly explain that I had two different stomachs - one for savoury (which was full) and one for sweet (which was empty and in desperate need of nourishment). Ok, ok, so I had two stomachs and this word is about a fourth...maths was never my strong point....good story though yeah? Um..time for a drink. #captionfail #abomasum #stilllovesugar #holycow
