Psycho Killer was released by Talking Heads in 1977 on their debut album Talking Heads: 77, with David Byrne singing the French and English lyrics about a troubled narrator. The repeated fa fa fa fa section became its most quoted hook, instantly signalling obsession and dark humour. As short video editing grew, creators clipped that chant for reveals, stalker jokes and horror parodies, and its use spread across TikTok and YouTube edits. It remains popular because the rhythm is instantly recognisable even without the rest of the song.
