Backpack is Dora's talking purple backpack in Dora the Explorer, the Nickelodeon children's series that began in 2000 and asked young viewers to repeat words and phrases aloud. The show's repeated call to say Backpack became one of its most recognisable routines, alongside Map and Swiper. Years later, short clips of the chant resurfaced in meme edits and short-form videos, where adults who grew up with the show reuse it for packing, travel and school jokes. Its simple rhythm and childhood familiarity keep it instantly recognisable.
