Goiabada is a popular Brazilian dessert made from guava fruit, creating a dense, sweet paste similar to fruit leather or a very thick jam.
In the song, the lyric "queijo sem goiabada" (cheese without guava paste) is a perfect example of the incomplete pairs the singer uses to describe herself without her love. This specific combination is a classic Brazilian snack called "Romeu e Julieta" (Romeo and Juliet), so the lyric cleverly implies that a perfect pair has been separated.
Have you ever felt so incomplete without someone that it feels like you're missing a part of yourself? That's exactly what this song is about. Adriana Calcanhotto uses a list of funny and sweet comparisons to describe this feeling. She says she's like an "Avião sem asa" (Airplane without a wing) or, in a classic Brazilian reference, "queijo sem goiabada" (cheese without guava paste). It's a list of things that just don't make sense on their own, from "Futebol sem bola" (Soccer without a ball) to the famous cartoon duo "Piu-Piu sem Frajola" (Tweety Bird without Sylvester).
But it's not all fun and games. The feeling is so intense that she says, "Eu não existo longe de você" (I don't exist far from you), and that "a solidão é o meu pior castigo" (loneliness is my worst punishment). She's so desperate to see her love again that she feels like time itself is against her: "Eu conto as horas pra poder te ver / Mas o relógio tá de mal comigo" (I count the hours to see you / But the clock is mad at me). It's a simple, direct, and powerful way to talk about missing someone so much it hurts.
