I'm always fascinated by airline jargon. And while writing a story, I was doing a little research about some odd airline terminology. My prime target was the word biffy, which is the universal airline term for an onboard bathroom (at least in my dictionary).

Ask any flight attendant where the biffy is, and he or she won't miss a beat in pointing you in the right direction--all while giving you that glare that says, "Don't even think about using the biffy in the first class cabin."

Well thanks to Google, I learned about a new product (and usage) for biffy, and not surprisingly its etymology is very close to home. 

As they say on the Web site, "I love my biffy!"
