The exact origin of Buton is unclear from the available metadata, and there is no verified title or artist attached to the file. What is clear is how it circulates online: people search for it by the short label, reuse it in anime-adjacent edits, and treat the unusual name as part of the meme. Sounds like this often spread through reposts, private chats, and small soundboard uploads rather than an official release, which is why they stay recognizable even when their source is hard to trace.
