Veigar is a yordle mage champion in League of Legends, Riot Games' long-running multiplayer battle arena game, and this line comes from his Brazilian Portuguese voice set. In Portuguese, 'acabou a brincadeira' means playtime is over, a fitting threat from a small villain who wants to be taken seriously. Brazilian players and creators have clipped it for short videos, streams and memes because it is instantly recognisable even without context, and it works as a compact warning before a comeback, a joke payoff or an overpowered play.
