What OS stands for? The question occurred to me when I viewed Coolnicsky's blog (Long time no update!). I knew OS meant "旁白、独白" in Chinese but I never thougut about where the abbreviation came from. As people saying "Acknowlege what is known as known, and GOOGLE what is not!", I G it and the answer is "Off Screen", not what I guessed like Outside Sound or Oral XXX...
OS also means Operating System such as Windows, Linux, Mac OS...
