The term 'stick (hopping toy)' is often referred to as a pogo stick, which is a four-letter word. A pogo stick is a device that is used for recreational hopping and jumping. It consists of a metal or plastic frame with two footpads attached to a spring-loaded pole. The user stands on the footpads and jumps up and down, using the pole to propel themselves into the air. Pogo sticks are popular among children and adults alike, and can be used for both fun and exercise.
