That may well be the case. i'd never heard it in any of my years in Nevada, Arkansas, or Texas, and left the States ten years before git (SCM) was a thing. It's certainly possible that it is/was regional and/or became a household word after 1997.

Even so... IMO you're doing yourself and your product a disservice by continuing that naming pattern.

> I have the same problem with "POS".

Agreed entirely :).
