NSFIB 

"NSFIB" stands for "not safe for intelligent beings," a humorous take on the common internet acronym NSFW (not safe for work), suggesting content that might be too absurd or unintelligent for any being to engage with

That guy posted some garbage that needs to be labeled NSFIB!

Not Safe For Face Book

Usually Posted in a status reply when something posted on Face Book is better suited to be explained in person to avoid ridicule or worse.

1) Joe Schmo- work sucked

Jane doe- really what happened

Joe Schmo- NSFFB. call me.

2) Joe Schmoe -I just got fired from work and dumped by my girlfriend all for getting tagged in a picture. I guess when you smoke weed with a naked girl make sure there are no cameras around, thanx Jim. Some pics are NSFFB.

NSFB 

Abbreviation for "Not Safe For Breakfast". Used in the same fashion as NSFW ("Not Safe For Work") to indicate a link with content that is particularly unsettling or disgusting. An NSFB link may or may not also be NSFW.

This link is SFW, but definitely NSFB.
