Mr. Popo is a supporting character in the Dragon Ball franchise, the diminutive attendant who watches over Kami's Lookout in the original manga and anime series. His polite, lilting speech made him a favorite for parody and meme edits, and this stretched-out bye became a standalone soundboard clip passed around in meme compilations and gaming chats. Creators keep reaching for it because the delivery turns an ordinary sign-off into a punchline, and its short length makes it an easy drop-in ending for videos, streams and reaction edits.
