Porra nenhuma is a very strong, informal, and somewhat vulgar Portuguese expression that literally translates to "nothing at all" or "absolutely nothing," often used to emphasize a complete lack of something.
In the context of the song, the singer uses it to vehemently deny that the other person ever truly loved them, stating "Amava porra nenhuma" (Loved absolutely nothing). This phrase adds a raw, emotional punch to the lyrics, conveying deep betrayal and anger.
"Amava Porra Nenhuma" is Tierry's blunt takedown of a partner who faked being in love.
The singer admits he fell for it: the promises, the easy "I love you," all of it sounded real at the time. Looking back, he realizes it was rehearsed, a line delivered with practiced ease rather than genuine feeling.
The chorus is the moment the mask comes off. Instead of a polite way of saying it, the song reaches for the rawest possible phrase: whatever that was, it wasn't love. He tells his ex to take that so-called love and shove it, because he knows now none of it was real.
It's a song about betrayal dressed up as a breakup anthem, angry rather than sad, and it doesn't pretend to be diplomatic about it.
