Sgommata literally translates to "skid mark" or the "screech of tires." It's a vivid and somewhat aggressive word that evokes a sudden, forceful action.
In the song, the line "Dura come una sgommata" (Lasts like a skid mark) is quite intriguing. It suggests something that is intense and impactful in the moment, but perhaps also fleeting or leaving a mark. It's an unusual and memorable simile that adds a raw, almost rebellious edge to the lyrics.
Bugo turns a bad back into a whole song. The title bends Che Guevara's slogan "Hasta la victoria siempre" into "Hasta la schiena siempre" (until the back, always), and the lyrics run on the same joke: "Ogni giorno uguale / Ma ti sembra normale" (every day the same, does that seem normal to you?), always watching "il movimento del bacino" (the movement of the pelvis). He brags "Ho un buon movimento di posta elettronica" (I have good email traffic), "Ma non passa mai il mal di schiena" (but the back pain never goes away).
The verses are a pile of odd images: "una scatola di cornflakes" (a box of cornflakes), "un sedile inclinato" (a tilted seat), "un cornetto all'amarena" (a sour cherry croissant) dropped "nel tritacarne" (in the meat grinder). The chorus is the easiest part to sing along to: "Vado su, vado giù, ho il mal di schiena" (I go up, I go down, I have back pain). It is good practice for everyday verbs like "vado" and "cadono", and for the phrase "mal di schiena", which Italians use all the time.
