play Solitaire. It's another to be looking at porn. Anything with nudity or partial nudity in it at all will often be labelled thus, on the off chance that a passing observer simply thinks you might be looking at porn.
So called because if you are caught reading these pages while at work, you can get in a LOT of trouble. For the more graphic NSFW pages, simply having them in the hard drive or cache of a work computer can get you fired. Even showing up in the server log files could be unhealthy.
Also applies to school, of course. Usually, even being caught visiting casual sites like YouTube, Facebook, or Dailybooth can get you in pretty big trouble there; being caught looking at anything deemed "pornographic" can result in suspension of technology access, a trip to the (vice)note principal's office, detention, suspension, or even expulsion. When it comes to school, anything crude or distracting from the educational experience (though the latter may be relaxed during breaks and lunch) qualifies for this trope, in addition to the above.
Also particularly helpful to parents who are at home - some people do have small children and still find time to netsurf. These same people like to have a warning to wait until the children are in another room before clicking a link.
NSFW can be applied to vulgar, violent, crude pornographic content. Also applied as a near-synonym for Squick. It may also be applied if the link requires sound, as not everyone has headphones at work (or should be wearing headphones, depending on the job).
It does NOT stand for "Now Show to Friends and co-Workers," no matter what the local troll may say.
Incidentally, get back to work before your Pointy-Haired Boss notices you slacking off by browsing this site!
