MXC, short for Most Extreme Elimination Challenge, was the American re-dub of the Japanese game show Takeshi's Castle, reworked with fast, jokey commentary over contestants tackling absurd physical obstacles. The phrase 'don't get eliminated' fits that format perfectly, because every round ended with players being knocked out in spectacular fashion. As clips from the show circulated online, the line became shorthand in gaming videos, reaction edits and elimination-style challenges, where a single warning can set up a funny failure without needing any explanation of the original show.
