A "High Five" is a celebratory gesture where two people raise one hand and slap their palms together. It is often used to express joy, congratulations, or camaraderie. The gesture is commonly seen in sports, social gatherings, and among friends, symbolizing shared success or happiness. The origin of the High Five is debated, but it gained popularity in the late 20th century, particularly in American sports. It is now a universal sign of positivity and encouragement, transcending cultural boundaries and often used in various contexts, from casual interactions to formal celebrations.
