Translation:Someone ate my cake in the refrigerator!
I have visions of someone climbing into the fridge and pulling the door closed behind them, then trying to find my cake. If I try to translate this I would come up with "ai đó trong tủ lạnh đã ăn bánh của tôi." It can't be corrected. It is just a phrase we would not use to describe taking my cake from the fridge and eating it.
