The shout comes from League of Legends by Riot Games, where Demacia is a proud kingdom and its champion Garen is known for yelling the name in battle. Garen has been part of the game since its early roster after its 2009 launch, and the line became one of his most recognizable voice cues. Clips of the shout spread through gaming videos, streams and soundboards as a shorthand for charging in with total confidence. It remains popular because even people who have never played recognize the heroic tone instantly.
