The phrase comes from Team America World Police, the 2004 puppet satire film by South Park creators Trey Parker and Matt Stone. In the movie, terrorist characters speak entirely in repeated variations of derka, mohammed and jihad as deliberate gibberish, mocking Hollywood depictions of foreign villains rather than using real Arabic. The derka derka derka chant became the film's most quoted joke, spreading through forums, gaming voice chat and early YouTube edits, and it remains a shorthand meme for unintelligible speech and over the top foreign accents in comedy videos.
