The phrase comes from Team America: World Police, the 2004 satirical puppet film by Trey Parker and Matt Stone, in which its terrorist characters speak in exaggerated mock Arabic gibberish instead of real dialogue. Derka derka became the most quoted example of that joke, and Mohammed Jihad was presented as a character name within the same parody. Clips circulated on early video sites and soundboards, then kept resurfacing in memes, edits and reaction videos because the chant is instantly recognisable even without context.
