Not suitable/safe for work (NSFW), not work-suitable (NWS), or not school-suitable (NSS) is Internet slang or shorthand. Typically, the NSFW tag is used on interactive discussion areas (such as internet forums, blogs, and community websites) to mark URLs or hyperlinks that may be sexually explicit or includes audio that contains profanity, so that the reader can avoid content that may be objectionable.
