The line comes from Django Unchained, Quentin Tarantino's 2012 western, where Dr. King Schultz is a bounty hunter who takes Django on as his partner. Spoken in Schultz's calm, educated manner, the short phrase travelled beyond the film as a soundboard clip and meme reaction, helped by its brevity and its clear meaning. Creators reuse it whenever a scene earns its payoff, from gaming victories and lucky finds to small everyday wins, because the line turns a modest success into a joke about deserving something good.
