Pirraça translates to "tantrum" or "childish fit." It's a vivid and somewhat informal word that perfectly captures a moment of immature behavior.
In the song, the singer admits, "Eu fui tão criança, imaturo, fiz pirraça" (I was so childish, immature, I threw a tantrum). This word is interesting because it's not as common as other terms for anger, and it specifically highlights a petty, childish display of frustration, making the singer's regret more poignant and relatable.
Dilsinho picks apart a breakup he caused, tracing it back to being "Imaturo, fiz pirraça" [Immature, I threw a fit] and ending up "de castigo" [punished] for it. The hook admits he knows exactly how her mind works and still won't be forgiven — "Não vai me perdoar" [You won't forgive me] — because "Saudade é dor que não passa" [Longing is a pain that doesn't pass].
The chorus turns into an inventory of missed chances: "Cada frase que eu pensei e não falei" [Every phrase I thought and didn't say], the kiss he never gave, the outfits he never noticed, the hugs he never held onto. He sums it up plainly — "Você me amou e eu descuidei" [You loved me and I was careless] — small details that, added up, cost him everything.
