The line comes from the Medic, a playable class in Valve's team-based shooter Team Fortress 2, whose German-accented voice lines became widely quoted by players in gameplay clips and online matches. Schadenfreude, a German word for pleasure at another person's misfortune, fits the character's darkly comic view of medicine and battle perfectly. As short soundboard clips spread through gaming communities, the single-word exclamation travelled beyond the game itself, becoming shorthand for gleeful mockery whenever a rival fails. It remains popular because it needs no explanation and delivers its attitude in under three seconds.
