The 'Orange Justice' meme originated from a Fortnite 'Boogie Down' contest in early 2018, where a boy known as 'Orange Shirt Kid' submitted a video of himself performing a unique, high-energy dance. Despite initially losing the contest, the community rallied behind him with the hashtag #JusticeForOrangeShirtKid, leading Epic Games to eventually add the dance to the game as a free emote titled 'Orange Justice.' The meme represents a triumphant underdog story and is widely used to express pure joy, victory, or a goofy sense of celebration after achieving a long-awaited goal or overcoming a petty obstacle.
