Agüito comes from the verb agüitarse, which is Mexican slang for 'to get sad', 'to get down', or 'to be disheartened'. It's a more informal and expressive way to say 'ponerse triste'.
In the song, the singer uses No creas que me agüito si pierdo de tus ojitos (Don't think I get sad if I lose sight of your eyes). This word adds a touch of authentic, regional flavor to the lyrics, making it interesting for learners to discover how emotions are expressed in different Spanish-speaking contexts.
Have you ever messed up so badly in a relationship that you'd do anything for a second chance? That's exactly where Victor Cibrian is in "Migajero." He's looking back, full of regret, asking, "¿Y quién podrá reemplazar tus besos? ¿Quién me podrá borrar tu recuerdo?" [And who can replace your kisses? Who can erase your memory?]. He admits, "Lo tuve todo y me hice el ciego" [I had it all and I played blind], and now he's stuck in his own sadness, feeling like "Fui un perdedor en mi propio juego" [I was a loser in my own game].
But even though he's feeling down, there's a glimmer of hope! He tries to play it cool, saying "No creas que me agüito si pierdo de tus ojitos" [Don't think I'll get sad if I lose your eyes] and "No es que me urja estar contigo" [It's not that I'm in a hurry to be with you]. But then he totally gives himself away, confessing, "Pero si quieres volver, me olvido hasta de lo que hice ayer" [But if you want to come back, I'll even forget what I did yesterday]. He just wants "un ratito pa' llenarte de besitos" [a little while to fill you with kisses] and to see her "aunque sea un poquito" [even just a little bit]. It's a really honest look at wanting to fix things after making a big mistake, even if it means swallowing your pride a little!
