Mr Slave is a recurring South Park character whose exaggerated catchphrase became one of the show's most quoted reaction lines in English and in the Latin Spanish dub, where he is called Señor Esclavo. Fans clipped the Jesucristo shout from the series and shared it across soundboards, meme pages and short video edits. Its appeal comes from that instantly recognisable distressed delivery, which signals panic without needing any context from the episode. It remains popular for reaction videos and chat replies where a normal response would feel too small.
