Supermattina is a playful, made-up word that combines "super" (meaning very or extremely) with "mattina" (morning). It's not a standard Italian word, which makes it unique and memorable.
In the song, Lorenzo Fragola uses it to describe a morning that feels particularly intense or difficult, perhaps after a long night. It conveys a sense of exaggerated morning blues, making it a creative and relatable expression.
"Super Martina" is Lorenzo Fragola's duet with Gazzelle about a fling that never quite becomes anything. The chorus sets the tone: he doesn't care if she leaves, he'll chase her through the streets anyway, and by tomorrow when he's sober he knows he'll just text her for a photo.
The title plays on the girl's name, Martina, and the Italian word for morning, "mattina" - a superlative morning after a superlative night. Gazzelle's verse fills in the other side: he wanted nothing more than to be alone, but she was older, more sure of herself, and had clearly done this before.
It's a light, self-aware song about a hookup neither of them is taking too seriously - equal parts attraction, hangover, and shrug.
