Inibido means "inhibited" or "shy." It's an interesting word because it describes a state of being held back or restrained, often due to shyness or self-consciousness.
In the context of the song, the singer is receiving mysterious calls every night and is clearly intrigued, but also feels a sense of inhibition or shyness about the situation. The word captures the emotional tension and mystery of the unknown caller, making it a compelling choice for a push notification.
In this song, the singer is caught in a confusing and tempting situation. He receives a phone call every night from a mysterious person and desperately wants to know their identity, pleading, 'me fala quem é você' (tell me who you are). This nightly call is becoming a 'castigo' (punishment) because he's already in a committed relationship.
He loves the woman in his life, calling her 'a dona do meu coração' (the owner of my heart), but the caller's 'voz tão atrevida' (daring voice) has 'messed up' his heart. He fears it's an 'armadilha' (trap) and worries that the secret caller might even be a friend of his partner, making the mystery both thrilling and dangerous.
