The lyrics of "Tesoura do Desejo" describe the meeting of two lovers in front of a bar in the Leblon neighborhood of Rio de Janeiro. The narrator, waiting nervously for his love to arrive, is overcome with fear when he sees her approaching dressed in black. He is afraid of starting up an old dream of being with her again, knowing that it will only turn into a nightmare. The fear is palpable, as if there is a sense of impending doom that is about to strike.

As they converse, he notices that she has cut her hair short. She explains that it was the "tesoura do desejo," or the scissors of desire, that inspired her to make the change. This expression brings to mind the idea that sometimes passion can be destructive, leading us to make drastic decisions in the pursuit of our desires. In this case, the woman has chosen to cut off a part of herself in order to fulfill the desire for change.

Overall, the song is a poetic exploration of the tension and uncertainty that comes with the pursuit of love and desire. It is a reflection on the choices we make in the name of passion and the potential risks that go along with those choices.
