Pirated version of a video game, downloaded in advance. Obtained before street date. Popularized on the gamefaqs message board Nonstop Gaming - General by user White Wolf Kiba (who may or may not actually be from Macedonia and have a difficult time obtaining legitimate copies of games).
Like "Alexander the Great was a Slav", this is meant to piss off greek people because they think that hes greek, but hes actually macedonian. His parents were literally Macedonian, and although he spoke greek and macdonians did adopt greek traditions, that doesne mean that hes greek.
