The sound comes from Kung Pow Enter the Fist, the 2002 martial arts parody written and directed by Steve Oedekerk, who also voices Master Betty. The film redubs and re-edits the 1976 Hong Kong movie Tiger and Crane Fists into a new comedy, with Betty as the theatrical main villain. His dubbed dialogue became some of the most quoted material from the film online, shared in clips, forums and soundboards. Fans still use Betty lines to signal over the top villain energy in jokes.
