Favored by many for her remarkable grace and beauty. Very intelligent and often flummoxes others with her stupendous vocabulary although benevolent. Her loyal nature makes her magnanimous and stoical. Curious yet genteel, she possesses the characteristics of a deity, by which she is coy,diligent and assiduous. But this is trumped by her vast elegance and beauty. Often described and leonine, due to her valorous and valiant actions.

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.
Dave: Man you'll never guess what..
Mike: What?
Dave: Just found out my girl has a Leanis.
Mike: You lucky motherfucker. Hold onto that one.
