Orgullo means "pride", but it often carries a more complex meaning in Spanish, touching on dignity and even stubbornness.
In this song, Carin Leon sings "No sé por qué el orgullo cuando tomo se tira a perder", which means "I don't know why my pride goes out the window when I drink". He's describing the internal battle of trying to maintain his dignity after a breakup, but losing that fight when he's vulnerable. It's a powerful word that perfectly captures the song's theme of heartbreak and regret.
This song is a classic tale of heartbreak after a few too many drinks. The singer is out with his friends and he knows he's about to make a mistake, so he begs them, "No quiero escribirle así que quítenme mi celular" (I don't want to write to her, so take my phone). He knows that when he drinks, his pride disappears. All he wants is to hug the person he's lost, but he has no idea where she is.
The title says it all: "Me está doliendo" (It's hurting me). He's so obviously miserable that he asks his friends, "¿Qué no están viendo?" (Can't you see?). He feels his heart is literally dying without her kisses. He's not trying to be mysterious or subtle about it; he says directly, "aquí te estoy extrañando" (I'm here missing you). He ends with a perfect summary of his problem: his heart was "Para amarte salió bueno / Pa' olvidarte salió malo" (Good for loving you / Bad for forgetting you).
