Yeah baby is the signature catchphrase of Austin Powers, the swinging-sixties British spy played by Mike Myers in Austin Powers: International Man of Mystery, released in 1997. Myers delivered the line with exaggerated confidence whenever Austin felt charming, lucky or victorious, and it returned across the film sequels. The phrase became closely linked to the character's retro style and comic swagger, then spread beyond the films into television, advertising and online memes. Creators still use the short clip as a quick, instantly recognisable punchline for success, attraction and self-satisfied celebration.
