Yogg-Saron is one of the Old Gods in World of Warcraft, introduced as the final boss of the Ulduar raid in the Wrath of the Lich King expansion. During the encounter, players hear his taunts, whispers and distinctive laugh as he tries to drive their characters insane. Clips of the laugh were later shared on YouTube and soundboards, where players and editors reused it outside the game. It remains popular because it instantly signals madness, menace and a powerful hidden villain, even to listeners who have never played the raid.
