What does NSFL stand for?

Not safe for life

NSFL is an acronym that means "not safe for life" and typically accompanies web content that is unsuitable for a person to see or hear. It is a variation of the popular NSFW acronym, but is applied to something that isn't good for someone in general, not just in a formal work setting.

NSFL often appears next to a link to the content on a website or email to warn the reader that the content is definitely inappropriate or offensive. If you receive an email or text message with NSFL you probably should just delete it because some things you just can't unsee.
