The sound comes from Money Heist, the Spanish crime drama first released in 2017, where Alba Flores plays Nairobi, one of the show's most spirited robbers. Her chikipum moment stood out because it broke the tension with humour and rhythm, and fans quickly clipped it for sharing online. As the series grew into a global hit, the short vocal riff travelled through fan edits, reaction videos and social posts, becoming a shorthand for confidence and playful mischief. It remains popular because it is instantly recognisable even to viewers who only know the show by reputation.
