Pisotear literally means "to trample" or "to stomp on." It's a strong verb that conveys a sense of disrespect and mistreatment.
In this song, the artist uses pisotear to describe how his ex-partner hurt him emotionally and took advantage of him. He sings, "como podía aceptar que de tantas maneras me pudieras pisotear" (how could I accept that in so many ways you could trample on me), highlighting the pain and humiliation he felt from her actions.
Yelsid's "Volverás A Mí" is a super relatable track for anyone who's ever been played for a fool. Our singer starts out with a bottle in hand, heart aching, listening to Juan Gabriel, and even laughing at himself a little. He's finally realizing how much he let his ex walk all over him, even though "Todo el mundo sabía y de mi se reían" [Everyone knew and laughed at me].
He's had enough of the excuses! Remember all those times she said the guy leaving her house at 3 AM was her cousin? Or those Facebook messages were just from "amigos que nada que ver" [friends who had nothing to do with it]? And how she wouldn't answer her phone when with him "por no interrumpir" [so as not to interrupt]? Now he sees it all clearly. He knows she was doing with five other guys what she was doing with him, and he's sure she'll come back crying and begging. He even says, "Voy a humillarte, de ti voy a burlarme" [I'm going to humiliate you, I'm going to make fun of you] when she's down. It's a blunt, honest look at getting over being cheated on and wanting a little revenge.
