The term 'Pogo' is a four-letter word that refers to a toy for bouncing. It is also known as a stick, and is a popular toy among children. The pogo stick consists of a metal or plastic frame with two footpads attached to it, and a spring in the middle. When the user jumps on the footpads, the spring compresses and propels the user into the air. Pogo sticks are a great way for children to have fun and get exercise at the same time.
