Arrefece comes from the verb arrefecer, meaning to cool down or get cold. It's a less common word than esfriar for the same meaning, making it more interesting.
In the song, the artist sings about a love "que aquece e não arrefece" (that warms and doesn't cool down). This metaphor beautifully conveys a love that remains passionate and never fades, highlighting the depth of his feelings.
Pensa Bem – which literally means Think Carefully – is a playful back-and-forth about two people trying to figure out what they really want from each other. The main voice is refreshingly honest: he is not looking for a fairy-tale romance, he is looking for a connection that is warm, exciting, and never cools down. At the same time, he tells the girl to stop assuming she has full control. If she thinks he would not be missed, she should think carefully before walking away.
When ProfJam jumps in, the flirtation turns up a notch. He brings swagger, word-play, and a reminder that no one here is made of iron. Both singers keep repeating the hook “Agora pensa bem, se não te faço falta” – “Now think carefully, if you do not need me” – challenging the listener and the girl to define the relationship. In the end, the song paints a vivid picture of modern love: equal parts attraction, doubt, and freedom, all served over an infectious beat that invites you to dance while you decide what you really want.
