A penis of biblical proportions, biologically curious in that both males and females may possess a Leanis. The origins of Leanises or, 'Leanai', are genetic - one cannot be grown, it must be born. In ages nine and younger, a Leanis will present as a smaller, but still formidable 'Stundnis'. In time, and with proper nutrition, this Stundnis will eventually mature into a fully fledged Leanis.
