What is Pogo-Sticking?

Pogo sticking occurs when a user performS a search, clicks on a result, very quickly clicks back to the search result page, and clicks on a different result. This means that when the searcher clicks on a link on a SERP, sees that it's not what he/she is looking for, immediately leaves by hitting the back button. Google doesn't like pogo-sticking at all. The reason why is very obvious: when users repeatedly visit your page, but don't stick around to read what you've written, it becomes apparent that the page doesn't really satisfy the users

A pogo stick is a device for jumping off the ground in a standing position, through the aid of a spring, or new high performance technologies, often used as a toy, exercise equipment or extreme sports instrument. It led to an extreme sport named extreme pogo or "Xpogo".

In simple words, Pogo Sticking means that when a website ranks highly but fails to satisfy the needs of people using that search term.
