The word "Brivido" literally translates to "thrill" or "shiver". It's a captivating word that immediately evokes a strong emotional or physical sensation.
In this song, Guè uses "Brivido" to express a deep yearning for intense emotion and genuine feeling in a world he perceives as numb and superficial. He's looking for something that can break through his apathy, making it a central theme and the title of the song.
The whole song is one long list of things that turn out not to be enough. "Più di un film, più di un drink, più della marijuana" (More than a movie, more than a drink, more than marijuana), and it keeps going: a suite in Copacabana, a rave in the middle of the savannah, rings, watches, banknotes, coke. Guè stacks up every reward a rap career is supposed to buy, then measures all of it against the one thing he cannot get, the shiver in the title. He is blunt about what that costs him: "Sono infelice di professione" (I am unhappy by profession). And the best line in his verse is the one that takes a swing at romance itself, "Farfalle nello stomaco, dammi l'insetticida" (Butterflies in the stomach, give me the bug spray).
Marracash takes the same numbness somewhere colder. His problem is noise. "Questo mondo fa troppo chiasso" (This world is too loud), too loud to hear his own thoughts, and then something worse: "Quello che è peggio non ricordo più quello che ho perso" (What is worse, I no longer remember what I lost). He gets one jab in at his country, "In un paese dove onesto rima con modesto" (In a country where honest rhymes with modest), and one at the rest of us posting through it, "Stati d'animo in centoquaranta caratteri" (Moods in one hundred and forty characters). Then he finally names what the title has been circling: "Un brivido che faccia breccia nella mia apatia" (A thrill that breaches my apathy). The hook comes back four times and never gets it.
