NSFOPW 

An abbreviation for "Not safe for other people's work."

I disagree that a photo of a woman's back with a knife in her neck is NSFW.

I think it's at best NSFOPW.

NSFHE 

Acronym for Not Safe For Human Eyes; Something so incredibly inappropriate or grotesque that it is not only unsuitable for work but for human eyes in general.

Goatse, Lemon Party, and Tubgirl are NSFHE.

NSFH 

The same as NSFW, but instead of work it’s not safe for home / house

That adult erotic art book you have isn’t NSFH, since you have children and all.
