Balbetto means "I stutter" or "I stammer". It's an interesting and somewhat uncommon verb to find in song lyrics, making it stand out.
In the song, Tananai uses it to describe his reaction when he sees the person he's singing about: "Guarda come b-balbetto" (Look how I s-stutter). This shows a moment of vulnerability and nervousness, suggesting he's so taken aback or overwhelmed by their presence that he can't speak clearly. It adds a touch of endearing awkwardness to the romantic context.
"Baby Goddamn" is a flirty, boastful party song. Tananai plays the confident charmer at a New Year's-adjacent bash, teasing someone he's into with lines about champagne, showing off on stage, and turning up the energy ("we're at fifty percent, imagine what we do at a hundred").
The chorus repeats "baby, what are you doing?" as he offers roses and promises devotion, but the song's twist comes at the end: he admits the romance never really worked out ("you weren't a boyband"), and the roses came with thorns. It's a light, self-aware take on a fling that fizzled, wrapped in a catchy, chant-along hook.
