That's just how I've heard the word being used.
And I hate how people use it like that.
I think it's funny how people take two root words, combine them so they make a sensible word, then the word gets shortened and recombined to make no sense.
For example:
- Auto + Mobile = Self Moving (A car)
- Automobile shortened to auto. No longer makes sense
- Auto body repair shop. Supposed to mean car body repair shop, really means self body repair shop, it's like doing surgery on your own body!
