Anjing Wibu comes from Indonesian meme culture, where wibu is widely used slang for a devoted, sometimes obsessive anime fan and anjing, meaning dog, is used as a blunt, humorous insult. The clip fits that online humour, using an animal voice to deliver a tease that feels light rather than hostile. It has circulated mainly as a short reaction sound in funny edits and chats, where viewers already recognise the slang. Its appeal endures because the joke is immediate, local and easy to reuse whenever anime fandom becomes the punchline.
