The line comes from South Park, where Stan and Kyle repeatedly shouted that Kenny had been killed after the character died in episode after episode. The gag became one of the show's most quoted catchphrases and spread far beyond television into memes, reaction videos and soundboards. This version keeps the same shocked delivery but swaps in Rush, a name familiar to gamers, making it fit deaths and eliminations in gameplay clips. That simple swap is why it still works: the joke is instantly recognisable, even to viewers who have never watched the original scene.
