Here's a word you may not know...
NSFW
NSFW stands for "not safe for work" and is usually used in conjunction with a link to a web site with content that may not be suitable for all people. It is considered polite to label such links as "NSFW" to avoid the embarrassment someone could incur if they followed the link to the web site while at work.
