Seo Joeli became known online through short forwarded WhatsApp audios in Brazil, where his drunken tchau brigado turned a routine goodbye and thank you into a catchphrase. The clip spread as a reaction sound in group chats and meme edits because it is brief, loud and instantly recognisable even without context. Users share it to close conversations, joke about drinking too much or give a mock polite exit, and its slurred wording is often written exactly as it sounds when people search for or caption the meme.
