Mr. Slave is a recurring character in the animated comedy South Park, introduced in the early 2000s as the overly dramatic partner of Mr. Garrison. Voiced by co-creator Matt Stone, the character became known for his high voice, leather outfit and theatrical reactions. His drawn-out Jesus Christ exclamation was clipped from the show and spread through forums, YouTube edits and soundboards as a standalone reaction. Because the delivery is instantly recognisable even without video, it survived as a meme shorthand for stunned disbelief long after the original episodes aired.
