Chulería is a fantastic Spanish slang word that means a kind of effortless cool, swagger, or charming cockiness. It's the special flair that makes someone stand out.
In the song, the main character Diego is described as having "chulería y ese punto de alegría" (swagger and that touch of joy). This single word perfectly captures his magnetic personality as he confidently walks into the club, ready to take over the dance floor.
Meet Diego, the star of Las Ketchup's monster pop track. When the clock strikes midnight, he steps right into a packed club dressed in an aquamarine suit ("su traje agua marina"), sporting moonlit eyes ("con la luna en las pupilas") and leftover party residue ("restos de contrabando"). The song describes him as an "afrogitano" (Afro-Romani) with a cool swagger ("chulería") who squeezes into the tightest spots on the dance floor ("donde más no cabe un alma") just to go all out ("darse caña").
The DJ spots him immediately and drops his favorite track, "el himno de las doce" (the midnight anthem). Diego gets swept up in what the song calls the "ritmo ragatanga", belting out the chorus: "Aserejé, de je, de jebe tu de jebere". It is pure gibberish, meant to mimic how a non-English speaker tries to rap along to an English song at full volume in the middle of a noisy club. He dances, enjoys himself, and sings at the top of his lungs without caring if the words make sense.
Las Ketchup are four sisters from Córdoba, in the Andalusia region of southern Spain: Lucía, Lola, Pilar, and later Rocío Muñoz. Their father is the flamenco guitarist Juan Manuel Muñoz Expósito, known by his nickname El Tomate, and the group took its own name as a nod to his. They grew up around flamenco before turning that background into pop music, working with producer Manuel "Queco" Ruiz to shape their sound.
In 2002 they released "Aserejé," known internationally as "The Ketchup Song," which topped charts across Europe, Latin America, and beyond and sold more than seven million copies. It anchored their debut album, Hijas del Tomate, which has sold over two million copies worldwide. They followed it with the singles "Kusha Las Payas" and "Un Blodymary," the latter also the title of their 2006 second album. The group has kept performing together since, reuniting for shows in Spain, Sweden, and Mexico well after their biggest hit first climbed the charts.
