Bisanggyeeomryeong is the Korean term for emergency martial law, a formal state measure in which military authority temporarily replaces normal civilian government during a national crisis. The phrase is instantly recognisable to Korean-speaking audiences and has circulated widely online in reaction videos, memes and political commentary, where its official, alarming weight is reused for comic exaggeration. Because the words carry real historical and legal seriousness in Korea, they work as shorthand for sudden, drastic authority even for viewers who do not speak Korean.
