PoPiPo began as a Vocaloid song by producer Lamaze-P, performed by Hatsune Miku and first shared online in 2008. Its lyrics celebrate vegetable juice, and the simple dance that grew around it helped the track spread through Nico Nico Douga and YouTube, where fans made dance covers, animated videos and remixes. The chorus became a shorthand for bright, nonsensical fun, so editors still reach for it when they want a clip to feel instantly cheerful, energetic and a little ridiculous.
