coup de foudre

The phrase "coup de foudre" literally translates to "a bolt of lightning" in French, but it is used metaphorically to describe love at first sight. It captures the sudden, overwhelming, and electric feeling of being struck by an intense romantic attraction the very moment you lay eyes on someone. It is a poetic and somewhat romanticized term. While you might use it in casual conversation, it carries a slightly dramatic or literary weight compared to simply saying "I fell for them immediately." It is almost exclusively used in the context of romantic sparks rather than general excitement about an object or a hobby.
