An attitude of strength, determination, and camaraderie, especially by the British people as a whole, during a difficult and adverse time or situation. Refers to the evacuation of allied troops from Dunkirk, France, carried out by several civilian boats during World War II. Primarily heard in UK. Our country faces the worst economic crises in decades, but I remain confident that, with a bit of the Dunkirk spirit, we can come out of this stronger than ever.
