Pippa is a common nickname for the statelier Philippa, though it now stands on its own. The name was brought into the limelight with the release of the 2009 film The Private Lives of Pippa Lee. We’d imagine any other Pippa to be just as carefree and upbeat.
Pippa’s effervescent ring makes it more befitting for a pet. As such, it's also prime for making up juvenile nicknames: Peppa, Pippapotamus, Pippy Long Stocking.
