Long Long Man comes from a series of Japanese television commercials for UHA Mikakuto's Sakeru Gummy candy, first released in 2017. The ads follow a couple whose relationship is tested whenever the mysterious Long Long Man appears with an extra long strip of the candy, set to a smooth jazz style song. Compilations of the saga spread widely online in 2018, turning the sung name into a standalone meme. The clip remains popular because the joke works without context: longer is treated as irresistibly better.
