Not safe for work
From VNDev Wiki
Not Safe For Work (often abbreviated to NSFW) is a category used to describe certain types of content that may be considered inappropriate for the workplace. Most commonly, this refers to sexual content, but it may also include violence, profanity, nudity, and/or potentially triggering content.
Not Safe For Life, or NSFL, is a more extreme version of NSFW, indicating that content is potentially severely triggering or graphic. This might include footage of a person's death or a graphic medical procedure.
