Derived from the latin root 'bambinnalino'; meaning 'torn leg-wear'. 'Bamby' is typically a term applied to polo trousers that have suffered large amounts of tear and wear due to harsh, often cheap, cleaning products. Whilst there is some debate about the limited scope of applying a term to only polo trousers, most all agree that should the term be used in regards to all leg-wear, the usage would be so frequent as to render most conversation incoherent.
