Prisencolinensinainciusol is a 1972 song by Italian performer Adriano Celentano, famously written in a language that is complete gibberish but phonetically designed to sound like American English. Celentano created the track to demonstrate how people are influenced by the sound and rhythm of music rather than the actual literal meaning of words. In internet culture, the song and its accompanying dance-heavy classroom video are used to represent moments of high confidence despite having zero substance, or the feeling of listening to someone who sounds like they know what they are talking about until you actually pay attention. It remains a viral favorite for its catchy beat and the surreal quality of its nonsensical lyrics.
