Ragatanga was released in 2002 by Rouge, the Brazilian girl group formed on the talent show Popstars, as a Portuguese adaptation of Las Ketchup's Spanish hit Asereje, also known as The Ketchup Song. The original chorus was inspired by a character trying to sing Rapper's Delight in garbled English, which explains the famous nonsense syllables fans still try to reproduce. Rouge's version became a defining pop hit in Brazil, selling widely and returning through nostalgia posts, dance recreations and meme edits that celebrate early 2000s Brazilian pop culture.
