This quote comes from Persona 5, where Morgana says "Looking cool, Joker" during battle moments involving the protagonist, Joker. The line became widely shared online because of its memorable delivery and the game's huge popularity after its 2016 release. Fans turned it into a reaction sound for anything that looks unexpectedly stylish, from gameplay clips to fashion edits. It is still used because the phrase is short, instantly recognisable to many players, and easy to pair with both sincere and ironic moments.
