Encerrona literally translates to a 'trap' or 'ambush'. It's a less common, more evocative word than typical synonyms for 'trap', often implying a surprise or a planned confinement.
In the song, the singer describes trying to get close to someone's mouth to "provocar una encerrona loca" (provoke a crazy trap). This suggests a playful, perhaps mischievous, attempt to corner or ensnare the person in a kiss, adding a unique and intriguing twist to a romantic gesture.
Vanesa Martín's "Sin Saber Por Qué" is all about that awkward, exciting push and pull when you're crushing hard on someone, and everyone else seems to notice it before you two do! She starts by feeling a bit clumsy, saying, "Me siento torpe no se que me pasa" [I feel clumsy, I don't know what's wrong with me]. She's trying to get closer, maybe even steal a kiss, but it's not going as planned: "Intento acercarme despacio a tu boca Y allí provocar una encerrona loca No, no lo hago bien" [I try to slowly get closer to your mouth And there provoke a crazy trap No, I don't do it well].
It's like she's dreaming of a perfect moment, imagining painting sunsets and writing their name in the snow, but in reality, there's this big, unspoken thing between them. The chorus really nails it: "Parece que todos lo ven Y yo sigo ahí sin saber por qué Excusándote, excusándome" [It seems everyone sees it And I'm still there without knowing why Excusing you, excusing myself]. They're both making excuses, prolonging the inevitable, even though their minds and hearts are clearly connected. She just wants them to "Ven, corre y besame" [Come, run and kiss me] and stop overthinking it!
