The phrase is a contracted, informal way of asking what someone did with a possession, and online it circulates mainly as a standalone reaction clip rather than a full scene. Its appeal comes from the abrupt ending, which leaves the object unnamed and lets viewers fill in the blank for their own situation. That openness has helped it fit many different edits, from gaming moments to everyday skits, where a short, puzzled accusation is funnier than a complete line of dialogue or an explanation.
