Hoshimachi Suisei is a Japanese VTuber with Hololive whose streams and songs have built her a large international fanbase, and short English lines like this one get clipped, shared and remixed across fan edits and meme videos. The 'hi honey' greeting works because it is instantly quotable, affectionate and easy to drop into almost any context, from stream intros to reaction memes. It sits naturally beside other short anime voice clips fans trade on soundboards, such as anime ahh, tuturu and onii-chan greetings, and it keeps circulating as long as creators want a cute, personal-sounding hello.
