The 'He Laughed' meme, also known as 'Roger Just Laughed,' is based on a legendary panel from the One Piece manga and anime. It features the Pirate King, Gol D. Roger, at the moment he reaches the final island, Laugh Tale. After a lifetime of searching for the ultimate treasure, Roger finds the story left behind by Joy Boy and bursts into uncontrollable laughter instead of claiming gold or power. This image has become an internet sensation used to describe a sense of overwhelming joy, the irony of a long journey, or a reaction to a 'joke' that only those at the pinnacle can understand. It captures the essence of adventure and the mysterious allure of the One Piece world.
