Marcelo Tinelli is one of Argentina's best known television presenters, famous for hosting the long running entertainment show ShowMatch and its dance competition Bailando. His big, expressive presenting style made many of his catchphrases and reactions familiar across Spanish speaking social media. Chau is the everyday informal word for bye in Argentina, and saying it several times in a row turns a normal farewell into a joke. Short clips of his voice have circulated on soundboards and in chat audios, which is why this stretched goodbye keeps being reused for comic exits.
