Conato is an interesting word because it can mean 'attempt' or 'impulse', but in a more dramatic context, it can also refer to a 'fit' or 'spasm', often associated with vomiting or a strong physical reaction.
In Bugo's song, the line "Un altro conato, poi stiamo insieme" (Another conato, then we're together) suggests a struggle or an intense, almost involuntary physical response, possibly implying a difficult or tumultuous situation before finding peace or togetherness. It's a vivid and somewhat unsettling word that stands out.
Bugo stages a date at sunset that keeps going wrong in gross, comic ways. He offers a handkerchief "In questo tramonto d'arancia" (in this orange sunset), then skins his knees; she smiles "con i pezzi tra i denti" (with pieces between her teeth) because "Hai mangiato una pantegana" (you ate a sewer rat).
The chorus shrugs it all off: "Stasera va così" (tonight it's like this), "Un altro conato, poi stiamo insieme" (another retch, then we'll be together). In the middle verse she has drunk "troppo veleno" (too much poison), the antidotes are harmful, and holidays could give her herpes. The "Pa para parà" refrain keeps it singsong, so the nausea plays as a strange love song.
