What is toodaloo?

"Toodaloo" is an informal, cheerful way to say goodbye. It's often used in casual conversations and has a lighthearted or playful tone. The phrase likely has origins in the French expression "à tout à l'heure," which means "see you later." Over time, it was anglicized into the current form, "toodaloo." This expression is commonly used in English-speaking countries and is viewed as somewhat old-fashioned or whimsical.
