In brief: each time a path was withdrawn and then reannounced (a "flap") in BGP some penalty points were given. Once a configurable amount of penalty points was accumulated the path was suppressed, i.e. not used for a configurable amount of time. It is a kind of "educational system" to achieve BGP stability. Because the approach had considerable drawbacks (see RIPE 378) it is now not recommended to implement route flap dampening.
As what Martin mentioned and the link he has provided, route flap dampening may more harmful than useful. However, it depends on the organization whether to remove it or keep/configure it as your mileage may vary.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
