Wuareando is a slang term, likely derived from "warear," which means to be under the influence of drugs or alcohol, or to be in a state of intoxication.
In the context of this song, it sets the tone immediately, describing a life consumed by substance abuse. The artist sings "Siempre wuareando en la misma esquina," painting a vivid picture of someone constantly getting high in the same spot, reflecting a cycle of addiction and despair.
Santa Fe Klan's "Wuare" is a really intense look at a life lost to addiction and despair. The song starts with him saying, "Siempre wuareando En la misma esquina" [Always 'wuareando' (a slang term for being high on inhalants, often glue or resistol) on the same corner], immediately setting a scene of constant struggle and a feeling of being stuck. He's lost everything, even his family, and he's always drinking, "De noche y de día Solo pa' olvidarme De lo mucho que sufría" [day and night, just to forget how much he suffered].
It's a really stark picture of a "Vida perdida Entre droga y bebida" [life lost between drugs and drink], and he admits he still can't find a way out. He talks about being "más de un mes Que no he bajado del vuelo" [more than a month that I haven't come down from the high] and feeling "Alucinado Voy buscando mi consuelo" [hallucinating, looking for my comfort]. He repeats that he hasn't gotten off the plane, meaning he's still high, "Emborrachado Perdido en el alcohol" [drunk, lost in alcohol]. The line "Todo volado Con mi bolsa de resistol" [all high with my bag of resistol] is pretty blunt about the specific drug use. He even says love left a wound in his heart that "Solo muerto se me quita" [only death will remove]. It's a really raw and honest song about hitting rock bottom.
