Nevoeiro is the Portuguese word for fog, and this clip comes from the Peppa Pig episode centred on Grandpa Pig and his lighthouse, described in Portuguese as the Farol do Vôvo Pig story. Peppa Pig is the British preschool series that began in 2004, and Grandpa Pig is Peppa's grandfather, often shown sailing and looking after the lighthouse. Portuguese dubs gave the scene a second life on soundboards, where the short blast was clipped on its own and shared as a reaction for mist, boats and low visibility jokes.
