Okey dokey is one of Mario's recurring catchphrases, delivered in the high-pitched, cheerful voice actor Charles Martinet gave Nintendo's mascot plumber for nearly three decades. The line pops up across the Super Mario series whenever Mario agrees, confirms or sets off, and its bouncy two-beat rhythm made it a natural fit for memes. Editors and streamers lifted the clip into reaction edits, gaming montages and short-form videos, where it now works as a universal stamp of cheerful approval far beyond its original games.
