Destapar literally means "to uncork" or "to open" a bottle. While it might seem like a common verb, its repeated use in this song highlights a specific theme.
The singer mentions, "creo que voy a destapar otra botella" (I think I'm going to open another bottle) and "Destapando botellas con toda mi raza" (Opening bottles with all my crew). This word is interesting because it's directly tied to the song's narrative of heartbreak and coping by drinking, making it a key action that drives the emotional state of the lyrics.
Ever been awake late at night, thinking about someone you miss? That's the heart of "3 De La Mañana." The song captures that painful feeling of being stuck after a breakup. It's 3 AM, and the singer can't sleep because he can't stop thinking about his ex. He wonders if she's already moved on with someone new, especially since she won't even open his messages. It hurts him to see her acting like she's over him, while he feels like he's going in reverse, unable to move on.
To cope with the pain, he turns to drinking with his friends, opening bottles of tequila, rum, and beer. He feels like he's losing control, drunk and a little crazy since she left. Despite the heartache and seeing her flirt with other people, he holds onto a sliver of hope. He admits he still gets excited every time he hears a knock on the door, wishing it might be her coming back. It's a raw and honest look at heartbreak, hope, and a long, lonely night.
