Arrastren comes from the verb arrastrar, meaning "to drag" or "to pull along the ground." It's a strong, evocative verb that isn't used lightly.
In "Para Que Regreses," the singer uses this word in a curse, wishing that his former lover be "dragged across the floor" by others. This intense imagery conveys the depth of his pain and desire for her return, making it a memorable and impactful word in the song.
Marca MP's "Para Que Regreses" is a super intense song about a love gone wrong! The singer is clearly heartbroken and, honestly, a little vengeful. He's not wishing his ex well at all. Instead, he hopes she faces a string of terrible experiences, all so she'll realize what she lost and come back to him.
He wishes for her to never find "un amor tierno y sincero" [a tender and sincere love], and for every man she meets to be "un estúpido" [a stupid person] who only uses her. He even hopes she's ignored when she asks for forgiveness, and that she's "ofendan, que te humillen día a día noche a noche
Hasta que llores" [offended, humiliated day by day, night by night, until you cry]. It's a pretty blunt way of saying, "I hope no one loves you like I do, so you'll return!" He truly believes that only through this suffering will she realize she belongs "conmigo" [with me].
