Arrebentava comes from the verb arrebentar, which literally means "to smash," "to break apart," or "to burst." It's a strong and somewhat aggressive verb that isn't commonly found in romantic ballads.
In the context of this song, the singer uses arrebentava in a highly suggestive and colloquial way to describe intense physical intimacy, implying a powerful and passionate sexual encounter. This double meaning makes it a very enticing and memorable word.
Have you ever heard about an ex who just can't let go, even when you've moved on? Well, Mc Jacaré's "Ouvi Dizer" is all about that! He's heard that his ex has found someone new, someone better even. He sings, "Ouvi dizer que você arrumou alguém melhor" [I heard you found someone better] and how this new person is perfect in everyone's eyes, even her parents'.
But Mc Jacaré isn't buying it. He thinks she's forgetting one crucial detail: "Que de noite tem saudade de mim" [That at night you miss me]. He's convinced that when it comes down to it, she still prefers him, especially "Na hora da cama" [At bedtime]. He's pretty blunt about it, saying she wanted him in the other guy's place and even brags about their past intimacy, making it clear he believes he was unforgettable. It's a bold and somewhat cheeky take on an ex who just won't fade away!
