Cacildis was popularised by Mussum, the stage name of Brazilian comedian and musician Antônio Carlos Bernardes Gomes, a member of the comedy group Os Trapalhões. On television in the 1970s and 1980s he built many jokes around adding is to the end of words, and Cacildis became his best known exclamation. The phrase survived through reruns, catchphrase compilations and later Brazilian meme pages, where the short audio became a ready made reaction sound that younger audiences recognise even without watching the original shows.
