Aurelion Sol is a playable champion in League of Legends, a celestial dragon who creates and commands stars, and his voice lines are known for their grand, condescending tone. His laugh fits that character perfectly, which is why League players began clipping it for highlight videos, streams and short-form edits rather than using a generic laugh track. It spread through gaming communities as a shorthand for arrogant confidence, especially after a dominant lane performance or a clean outplay. Because the character remains recognisable, the clip still works even for viewers who do not play the game.
