Wawa wasi is a fascinating and somewhat rare term in Spanish music, especially in a Dominican context. It's a Quechua phrase that literally translates to "baby house" or "nursery".
In this song, Rochy RD uses it in a metaphorical and somewhat derogatory way. When he sings, "por un wawa wasi dejarme solo," he's implying that his partner left him for someone or something trivial, immature, or perhaps even for a situation that's like a "baby house" – something childish or insignificant. It's a unique slang term that adds a layer of cultural depth and a bit of a jab to the lyrics.
Rochy RD's "Dile A Tu Amiga" is a super direct message to an ex, telling her to let her friend know that their relationship is officially over. He's moved on completely and doesn't feel anything for her anymore, even though he used to be head over heels!
He even says, "no tengo memoria por lo que no tiene" (I have no memory for what doesn't exist) and "mi corazón borró contigo y mi cuerpo ya no se acuerda vivir" (my heart erased you and my body no longer remembers how to live). It's a pretty savage way of saying he's totally over it. He feels good about it too, because he doubts she'll find someone who loves her and, as he bluntly puts it, "en la cama te lo haga bien" (does it well in bed). Ouch! It seems like her friend might have even played a role in their breakup, as he mentions, "tu amiga coronó bebés o no tu amigas sino tú alcanzó a puso y se propuso separar no finalmente lo logró" (your friend won, baby, or not your friend but you managed to propose and set out to separate us, finally achieved it). This song is all about moving on and not looking back, with a bit of a boastful edge.
