NSFWFH
Not Safe For Work From Home
Content, usually a photo that is inappropriate for the work place is deemed NSFW (not safe for work) as co-workers may be offended. With shelter-in-place rules due to COVID-19, many people are working from home with family present.
NSFWFH is the modern variation of NSFW.
