The hook, "Loco, tu mujer es una perra, una diabla" (Bro, your girl is a bitch, a she-devil), is followed straight away by the joke it was built for: "Mira cómo me ladra y me dice" (Look how she barks at me and says), and then the barking itself. Two lines, setup and punchline, repeated until it stops being a joke and turns into the beat.
The verses are where the story actually sits. He is out on the corner in his sneakers when she turns up, "Fumando marihuana, me dice, '¿Qué es lo que pasa?'" (Smoking weed, she says to me, 'What's going on?'), and his answer is to back away from the whole thing: "No quiero tener coro con esta situación" (I don't want any drama with this situation), because "Como se entere su padre, el que se va enterar soy yo" (If her father finds out, the one who gets it is me). The refusal is self-interested rather than noble, and he says so. By the outro he has dropped the subject entirely and is shouting out his crew and promising "yo voy a ser el número uno" (I'm going to be number one), which is about the level of reflection this song is going for.
