Could one of you whippersnappers tell me what NSFW stands for?
My guesses:

No such f-ing way!

or more likely:

Not safe (or suitable) for wimps (or women or wombats or wussies or Washington)

Not safe for work.  It indicates something that you'd probably rather not have on your screen if a coworker happens to walk into your office.
