The phrase comes from the theme song of Sitio do Picapau Amarelo, the Brazilian television series based on Monteiro Lobato's children's books. Singer and composer Gilberto Gil wrote the opening with a chain of fruit sweets, including marmelada de banana, bananada de goiaba and goiabada de marmelo. The rhyme became familiar to generations who grew up with the show. Online, short cuts of the line circulate as a nostalgic meme sound, reused in edits, chats and videos whenever bananas, desserts or childhood memories appear.
