Partorito is the past participle of the verb partorire, which means "to give birth". It's a powerful and emotionally charged word, especially in the context of this song.
In "Mamma", GionnyScandal uses this word to directly address his birth mother, who abandoned him. He sings, "Mi hai partorito e mi hai lasciato giù" (You gave birth to me and left me down), highlighting the profound sense of abandonment and betrayal. This word is central to the song's raw and poignant narrative about his origins and his relationship with his biological parents.
"Mamma" is GionnyScandal's raw account of growing up without ever knowing his parents. He never saw his father's face and never even learned his mother's name. He was left on a sidewalk with nothing, raised by people who weren't his family.
The chorus circles back to one aching question: if his parents had actually wanted him, where would his life be now? He still doesn't know who his mother is, and asks what fault a newborn baby could possibly carry.
By the second half he turns defiant. He's become famous with no parents behind him, and he challenges whoever abandoned him to face what they did. The song ends the way it started, with a childhood question that never got an answer.
