Tidus is the main character of Final Fantasy X, released in 2001, and this laugh comes from a scene where he tries to teach Yuna how to laugh on command, resulting in a deliberately unnatural performance that players remembered long after finishing the game. Clips of the scene spread through video compilations, forums and later short-form video, where the laugh was detached from its story and reused as a standalone reaction. Its lasting appeal comes from how instantly recognisable the forced rhythm is, even to people who have never played the game.
