The line comes from Barbie Girl, the 1997 Eurodance single by Danish pop group Aqua, sung as a call and response between Lene Nystrøm and René Dif. The song topped charts internationally and became one of the defining novelty pop hits of the late 1990s, built around a plastic, doll like party world. Decades later the hook keeps resurfacing in short form edits, costume reveals and nostalgia posts, helped by renewed interest in Barbie as a pop culture figure, because the phrase alone instantly identifies the song.
