The Ghost Duet meme originated from a charming 2017 animation by artist and musician Louie Zong, featuring two simple white ghosts singing a short, harmonized melody. The video quickly went viral for its lo-fi aesthetic and incredibly catchy tune, eventually becoming a staple of 'wholesome' internet culture. Users typically use the template to represent two entities in perfect harmony, whether it's two friends sharing a single brain cell, a person and their pet, or even just two concepts that fit perfectly together. Its resurgence on platforms like TikTok and Instagram has solidified the ghosts as icons of simple, joyful digital expression.
