Basically it is also a category of some things that is to be shared that is often inappropriate and contains mature content.

Bob: Hey bro, what does NSFW stand for?
Billy: It stands for "Not For Showing Wife".
Bob: Does that mean porn?
Billy: I guess you could say that...

Nipple-sucking farm workers.

Because working the fields can get awfully boring without some NSFW.

1) Not Safe/Suitable For Work. An acronym that could get you fired if your boss sees or a co-worker snitches you out for browsing inappropriate material on the internet, especially if it's nudity.
2) Nude/Nudity Shots/Scenes Fucking Win. A made up acronym I personally thought it stood for when viewing ecchi and sexy hentai photos on Twitter. Although I was wrong I still think this acronym fits better.

1) Billy got fired from the office because Kevin snitched him out for googling nudity pics on the company's PC. Moral of this incident: Don't view material that is nsfw.
2) These pics of Yamato make me gap 24/7. Her nsfw.
