The Good Grinch meme originates from the classic 1966 animated television special 'How the Grinch Stole Christmas!', based on the book by Dr. Seuss. It specifically features the moment the Grinch experiences a change of heart, symbolized by his heart growing three sizes. In internet culture, this version of the character—often seen with a wide, genuine smile—is used to represent wholesome moments, unexpected kindness, or the feeling of finally being won over by something positive. It serves as the perfect antithesis to the 'Mean Grinch' or 'Grinch Plotting' memes, celebrating transformation and holiday cheer.
