Estrujarme comes from the verb estrujar, which means to squeeze, wring out, or crush. It's a vivid and somewhat aggressive verb that isn't used in everyday conversation as often as more common verbs for touching.
In the context of this reggaeton song, the lyric "Ahora te toca estrujarme el pantalón" (Now it's your turn to squeeze my pants) is a playful and suggestive invitation to dance closely and intensely. It implies a passionate and physical interaction on the dance floor, making it an engaging and memorable word for learners.
This is a straight-up perreo anthem, built to get a room moving before the first verse even lands. It opens with an actual introduction: “Damas y caballeros” [Ladies and gentlemen], the duo announcing themselves like a DJ hyping the room before the beat drops. Then Wisin gets straight to it, asking someone what they've got on the dance floor: “Bonbón, quiero saber que tiene allá atrás” [Babe, I want to know what you have back there].
The hook does the real work here: “Ven, baja, rompe el piso, sube, sube” [Come, go down, break the floor, go up, go up] is a dance instruction as much as a lyric, and “Ese booty tú lo sacude'” [That booty, you shake it] leaves nothing to guess at. From there it's one long boast about the party: girls doing shots and getting fierce, “Ella mata a las envidiosa' a sangre fría” [She kills the jealous ones in cold blood], and a closing verse that compares getting someone dancing to landing a punch, “A darte un nocaut en ese booty como Floyd” [To give your booty a knockout like Floyd]. It's loud, explicit, and doesn't pretend to be anything else.
