The line comes from The Hunger Games, Suzanne Collins's dystopian story first published as a novel in 2008 and adapted into the 2012 film, where it is used as the official greeting before the televised games begin. In Spanish versions it appears as Felices Juegos del Hambre, keeping the same festive wording for a brutal contest. Clips of the greeting circulate in edits, parodies and competition videos because the phrase is instantly recognisable, and its cheerful formality still works as shorthand for a contest about to turn serious.
