Te pille comes from pillar, an informal verb meaning “to catch” or “to get.” In the line “espera a que te pille” (“wait until I catch you”), it has a playful, flirtatious tone, making this slang expression especially memorable for learners.
Kidd Voodoo, from Chile, is stuck on a girl he calls "nena mala" [bad girl], and he can't decide whether that's a warning or a compliment. He opens by saying "Recordarte siempre es una bala" [Remembering you is always a bullet], which is a blunt way to say that even thinking about her hurts. The chorus blames it all on "sensacione' que me parten el corazón" [feelings that break my heart]. Notice the dropped final s there: Chilean speech swallows it, so sensaciones becomes sensacione' and todos los caminos becomes "to' los camino' llegan a ti" [all roads lead to you]. Same with "estás quitá'" [you're out of it], short for quitada, and "dañá'" [damaged], short for dañada.
What I like is that he isn't the hero of his own story. He admits "ni yo me entiendo" [not even I understand myself], and he refuses both roles she might hand him: "Yo no quiero ser tu sombra ni el que te repare" [I don't want to be your shadow or the one who fixes you]. Then the last verse goes soft and a little silly, blaming his bad luck on one thing: "es culpa de tus ojitos verde'" [it's the fault of your little green eyes]. The -itos ending is affection, not size. Rolling his whole heartbreak onto her eye colour is a bit much, and that's exactly why it works.
