Currently, they're intended for use on the Move pages to show how the moves have been changed over time in their own section, like here. "Buff" is a common word in gaming for improvement, while "Nerf" represents the same for adding weakness. However, they're only used for the template names as a shorthand, to avoid confusion for more casual users.
