The phrase comes from Dutch reality star Martien Meiland, who became a household name with the SBS6 series Chateau Meiland from 2019, following his family renovating and running a chateau in France. His exaggerated, feel good exclamations became the show's calling card, and wat goed was clipped and shared widely on Dutch social media and messaging apps. Fans began using it outside the show as shorthand for delighted approval, and it remains his most quoted line in edits, remixes and reaction videos across the Netherlands and Belgium.
