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.

NSFH 

Not Safe For Homosexicles -- a phrase, image, video, or song that has the potential to offend faggots.

{Seen in the description of a YouTube video of a drone flight}:

I also added NSFH (Not Safe For Homosexicles) because one of the songs does have the potential to be mildly offensive to some members of the LGBTQ+ community.
