Well, you could ask the National Aeronautics and Space Administration, the Central Intelligence Agency, or even consult with the Massachusetts Institute of Technology. Perhaps you can send them JavaScript Object Notation using the Asynchronous Javscript and Extensible Markup Language standard over HyperText Transfer Protocol?

I use acronyms to reduce the cognitive overhead of reading, and (relevant to this discussion) make otherwise offensive terms acceptable in a broad range of environments (snafu, CYA, OMFG, WTF, etc). I'm sorry you haven't run across CYA before (though that might be a good thing), but it's not a terribly uncommon acronym either.
