The Drooling Face emoji depicts a smiling face with drool dripping from one corner of its mouth. It is commonly used to express extreme desire or craving for something, whether it be food, a person, or an object. It can also be used in a more literal sense to represent drooling, such as when someone is asleep and drooling. The emoji was added to Unicode 9.0 in 2016 and has since become a popular way to convey excitement or hunger in digital communication.
