Chifre literally means "horn" in Portuguese. However, in Brazilian Portuguese slang, it's commonly used to refer to "cuckoldry" or being cheated on.
In the song, the line "Segunda chance é igual segundo chifre" (A second chance is like a second cuckoldry) uses this double meaning to powerfully convey the singer's refusal to forgive. It implies that giving a second chance to an unfaithful partner is akin to inviting them to cheat again, making it a very impactful and culturally specific word choice.
Marília Tavares turns heartbreak into a power anthem in Segunda Chance. Over a catchy Brazilian sertanejo beat she calls out a partner who was great in bed but lousy at loyalty. The lyrics hit hard: if you can betray once, you can betray again, so forgiving you would be like saying “Go ahead, repeat the mistake.” Her vivid comparison of a “second chance” to a “second pair of horns” (another act of infidelity) shows just how little faith she has left in this love.
The song is a fiery declaration of self-respect. With lines like “Te amar já foi um erro / Voltar é burrice” (“Loving you was already a mistake / Going back would be stupid”), Marília shuts the door on past pain and invites listeners to do the same. It is a reminder that real love and real fidelity should exist together, and if they don’t, walking away is the smartest, strongest move you can make.
