Although it's spreading farther and farther on TikTok and in real life, jit is not a brand new word, and it seems likely that it wasn't created first on TikTok. There are videos explaining what the word means that are almost a year old, and it seems like it's been popular among young people for even longer than that.

TikTok is often responsible for spreading slang terms around to people who may never encounter them otherwise, and in some cases, new words or phrases are created specifically because of the platform. In the case of jit, though, it seems more likely that the term already existed out in the world, and people are just now using it with more and more regularity on TikTok.

Jit is not the first term that TikTok has spread to a much wider audience, and it's unlikely to be the last. Some of these slang terms have become a lasting part of our vocabulary, and others have come and gone pretty quickly. Everything from "glazing" to "ate" has been popular on the platform at one time or another.

Thankfully, for every TikTok video that uses a term you may not understand, there's probably one that explains what that term means. The internet can be a confusing place filled with strange terminology, but that's why they keep making new dictionaries.
