Rimborsano comes from the verb rimborsare, meaning 'to refund' or 'to reimburse'. It's a word you might not expect to find in a rock song, making it quite unique and memorable.
In the context of the song, Ligabue sings, "Soddisfatti o no qua non rimborsano mai" (Satisfied or not, here they never refund). He uses this financial term metaphorically to convey that life doesn't offer second chances or take-backs, emphasizing the finality of our choices and experiences.
Ligabue sings about feeling out of step with the times. The people in this song don't wake up in time, don't dress or laugh or love the way everyone else seems to, and carry dreams that feel too big for their ordinary faces.
Life only gives you one shot, and there's no refund for the years you spend chasing something that doesn't quite fit. Instead of forcing themselves to catch up, the people here just keep dreaming, getting knocked down, and picking themselves back up anyway.
The chorus circles the same idea from a few different angles: maybe it isn't their moment right now, and maybe it never will be. But the song isn't really about giving up. It's about wearing that mismatch with a stubborn kind of pride.
