The phrase comes from Dutch, where mijn gestolen broodje means my stolen sandwich and the original caption asks who stole it. No widely documented film, show or creator source is attached to the clip, so it circulates mainly as a standalone soundboard reaction. Its spread relies on the universal joke of treating missing food like a crime scene. Short, quotable voice clips like this travel easily between chats, edits and meme pages, where the sandwich line becomes shorthand for any petty, food related loss.
