Wannabe is an English loanword directly incorporated into Italian, meaning someone who wants to be or imitate another, often famous, person or group.
In the song "Giovani Wannabe," the Pinguini Tattici Nucleari use it to describe a generation of young people who are perhaps still finding their identity, aspiring to something bigger, or imitating trends. It's an interesting choice because it's a foreign word that has become common in Italian youth culture, making it both recognizable and unique in a song title.
"Giovani Wannabe" (Young Wannabes) is Pinguini Tattici Nucleari's snapshot of a modern relationship stuck between real intimacy and constant distraction. The singer notices his partner's heart, and later her phone feed, holds only photos of landscapes with no room for him, yet he still can't stop watching her.
The lyrics swing between tender, over the top declarations (reading the meaning of life on her legs, forgetting the Bible and Freud) and a string of pop culture references: Hendrix's guitar, Dorian Gray's untouched portrait, the Big Bang, Kerouac's On the Road, Spock's planets. All of it turns two ordinary young people into "wannabes" chasing something much bigger than themselves.
By the end he admits it might be simpler to just stay friends, but he keeps coming back, dedicating the highway to the sea to her and asking to be taken anywhere, as long as it's far from the routine he's trying to outrun.
