41. What does DNI mean on TikTok?
If you've seen 'DNI' anywhere on TikTok, it means 'Do Not Interact'. The internet acronym is mostly used by users who share NSFW and adult content that is not meant for anyone under the age of 18. The phrase allows users to signpost that they will not interact with underage people, and signifies a content warning to minor users. Users also use DNI when they don't want to interact with people who support or follow certain things.
