What does “mission accomplished” mean in English?

“Mission accomplished” means you have finished your goal successfully. In the video, someone is secretly buying everything a friend touches in a store. When the friend finally picks up an item the person wanted her to touch, the buyer says “Mission accomplished!” — the secret plan worked. This phrase is used in everyday English to say that a plan or task is complete. It is often said with a feeling of satisfaction or light humour.

The phrase comes from military language, where a “mission” is a specific task given to soldiers. “Mission accomplished” means the soldiers completed what they were asked to do. Today, people use it in everyday situations — finishing a project at work, completing a shopping list, or even just successfully making a difficult phone call. You might say: “I finally fixed the printer. Mission accomplished.” The phrase can also be used with light sarcasm — for example, after completing a very small or silly task. It is informal and friendly in tone.
