This is a reggaeton brag about a girl who knows exactly what she wants, and J Alvarez and Lenny Tavárez are more than happy to go along with it. It starts on the dance floor: "Yo la conocí y me le pegué" (I met her and I stuck close to her), then "perreándonos me la besé" (while we were grinding I kissed her). Perrear is the reggaeton dance itself, so you will hear it a lot in this genre.
The chorus is a shrug: "Pues sí, ¿pa' qué?" (Well yeah, what for?), as in why pretend otherwise. He admits she is a bit toxic, "Tiene de tóxica, pero yo no me alejo" (she's got some toxic in her, but I don't walk away), and that she plays it straight with him: "no me coge de pendejo" (she doesn't take me for a fool). There is a baseball joke too, "Si me agarra el bate, la saca del parque" (if she grabs my bat, she hits it out of the park), and a shout-out to Puerto Rican legends: "Tego Calde'" is Tego Calderón and "Como Yandel" names the Wisin & Yandel star. Fair warning: the lyrics get very explicit, so this one is strictly for grown-up ears.
