Escalofríos translates to "chills" or "goosebumps". While it can refer to physical chills from cold or illness, in this song, it's used to describe a powerful emotional reaction.
Tito El Bambino sings, "Me emocioné, tanto que te lo juro me dio escalofríos" (I got so emotional, I swear it gave me chills). This word captures the intense excitement and thrill he feels in a romantic moment, making it an engaging and evocative choice.
Tito El Bambino's "Desnudarte" is a super direct and passionate song about a night of unexpected intimacy. The singer is totally thrilled about what happened, even if the other person might regret it later. He sings, "No me eches la culpa a mí / Si luego te arrepientes de lo que hoy pasó / En realidad que a mí me encantó" [Don't blame me / If later you regret what happened today / In reality, I loved it].
He's been wanting this for a while, and he's not shy about admitting how much he enjoyed every moment, repeating, "Me encantó desnudarte / Me encantó tocarte / Y besarte todita tu piel" [I loved undressing you / I loved touching you / And kissing all your skin]. He even admits to getting chills from the excitement! There's a hint that the other person might be a bit guarded, saying they don't believe in love, but for him, this connection was real and meant something. He doesn't want them to think he's not serious about what happened, because that would hurt him.
