The jingle comes from Granblue Fantasy, Cygames' long-running fantasy role-playing game, where SSR is the highest rarity for characters and weapons obtained through its gacha draws. Because those pulls are rare and often saved for gala events with boosted rates, players began recording their reactions and sharing the sound with pull videos, streams and edits. It spread through the game's community as shorthand for finally getting lucky, and it remains popular because it instantly tells other fans what happened without any explanation.
