Battlefield V is a World War II first person shooter developed by DICE and released in 2018, with German and British forces among its playable factions. Its multiplayer matches are filled with short contextual voice lines in each faction language, including callouts like enemy spotted, warnings and taunts triggered during combat. This German line was lifted from that chatter and shared on soundboards, where its literal meaning, today is your lucky day, made it reusable far beyond the game. Players keep using it as an ironic luck tag for clips, streams and edits.
