The phrase comes from everyday Brazilian Portuguese internet slang, where tbm shortens também, meaning also or too. Clips like this circulate on soundboards and messaging apps because the wording is instantly understandable to Portuguese speakers while K-pop gives it a clear fandom context. Its humour depends on timing rather than a known speaker or source recording, so it is shared as a generic reaction audio. The short length and abrupt delivery helped it fit edits, chat replies and meme compilations built around music taste and fan identity.
