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.
This song is all about a guy named Diego, a local legend who is the life of the party. The lyrics describe him as a cool, happy-go-lucky character with a unique "Rastafari afrogitano" [Rastafari Afro-gypsy] style. He shows up at the club dressed in his "traje agua marina" [aquamarine suit] and is ready to dance, even when there's no room on the floor.
The best part is what happens when the DJ, who knows him well, plays his favorite song. Diego gets so into it that he sings along, but he doesn't actually know the words! The famous chorus, "Aserejé, de je, de jebe tu de jebere," is just Diego's fun, made-up version of the lyrics. He just dances, enjoys it, and sings his heart out anyway, which is what the song is all about.
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.
