Fire is a universal symbol for passion in France. This phrase dates back centuries. It suggests a fire that is burning at its peak. In French culture, showing too much emotion can sometimes be seen as 'too much.' But tout feu tout flamme is a fond way to describe it. It acknowledges the intensity without being mean. It reflects the French appreciation for 'le coup de foudre' (love at first sight) or sudden inspiration.
