Rengar is a champion in League of Legends, Riot Games' team-based arena game, where he plays as a lion-like hunter who stalks enemies from brush and strikes without warning. The fear sound is tied to that predatory playstyle, marking the moment a hunt turns into a panic-inducing ambush. Clips of the effect have circulated in gameplay montages, highlight reels and meme edits, where editors reuse it outside the game to signal sudden danger. It remains popular because the snarl is instantly recognisable to players and works as shorthand for being hunted.
