Sounds good to me. Maybe it's bit of both - that is, the term was first coined as the name of a specific programming function, and then adopted more widely on the analogy of "sox" etc. I believe this has happened before, especially in the field of computer jargon; management types hear software developers using an apparently misspelt word and start using it themselves so as to look cool. No time to think of an ecample - it wouldn't be the first time though.
