Cabrón is a versatile and very common slang term in Spanish, often used to mean 'asshole' or 'jerk', but its meaning can shift significantly based on context and tone.
In this song, the lyric "Que por qué ando de cabrón" translates to "Why am I acting like an asshole?" Here, it's used in a self-deprecating way, acknowledging that his behavior might be perceived negatively after a breakup. It's an interesting word because it's so prevalent in informal Spanish and understanding its nuances is key to grasping everyday conversations and song lyrics.
This song is a whole conversation about a breakup, but the crazy part is who he's talking to: his ex-girlfriend's mom! Junior H starts by describing a tense moment with his girlfriend, where he knows things are ending. He's already thinking about having to "borrar fotos y videos" [delete photos and videos] and just like that, "se fueron nuestros recuerdos" [our memories are gone]. He feels like she's changed and doesn't know why.
Then the story shifts. Her mom confronts him, asking why he's acting like a jerk, "que por qué ando de cabrón" [why I'm being an asshole], and pointing out his new tattoos and this whole 'sad boy' vibe. His answer is so blunt and honest. He tells her he gave her daughter everything, that her kisses are like permanent tattoos on him, and then hits her with the final line: "¿Doña, qué hago si su hija me lastimó?" [Ma'am, what do I do if your daughter hurt me?]. It's a classic corrido tumbado move, mixing heartbreak with a tough, straightforward attitude.
