The earliest uses were spotted in:
- Reddit threads as part of fictional jokes.
- Group chats as a weird reply or filler word.
- TikTok comments where it added a chaotic, “you had to be there” type of humor.
Its growth seems fueled by confusion and curiosity. The fewer people who understood it, the more others wanted to use it.
