Fortnite is a free-to-play battle royale game from Epic Games that launched in 2017, and its Battle Pass is the seasonal progression system where players unlock skins, emotes and other rewards by playing. The pass jingle became familiar to millions of players who heard it every season, and it later spread beyond the game as a short audio meme in gaming videos, streams and TikTok edits. It is still used because it instantly signals achievement, progression and a new season starting, even for viewers who only know Fortnite from clips.
