Desacatarme comes from the verb desacatar, meaning to disobey or disregard. It's a less common word in everyday conversation, making it stand out.
In the context of this song, the singer is expressing a desire to "desacatarme" (disobey/disregard) the usual rules and routines of life, especially on the weekend. They want to let loose, party, and forget about responsibilities until Monday morning, highlighting a carefree and rebellious spirit.
Get ready to shake off the work week with Los Hermanos Rosario's "El Cuerpo Lo Sabe"! This song is all about that amazing feeling when Friday evening arrives, and all you want to do is forget about your responsibilities and just dance. The singer is ready to leave work and immediately go pick up their loved one, declaring, "Saliendo del trabajo voy a pasar a buscarte esta noche vamos a bailar" [Leaving work, I'm going to pick you up tonight, we're going to dance].
It's a celebration of letting loose and enjoying the moment. They want to "olvidar la rutina" [forget the routine] and just have fun until the party ends. The lyrics make it clear: "que llegó el fin de semana y no queremos con la cama" [the weekend is here, and we don't want to stay in bed] and "hasta el lunes en la mañana no quiero saber de nada nada" [until Monday morning, I don't want to know anything at all]. It's a fun, energetic invitation to hit the streets and dance the night away because, as the title says, "El cuerpo lo sabe" [The body knows it] – it's time to move!
