Bârfeau is the past tense form of the verb "a bârfi", meaning "to gossip". It's a wonderfully specific and expressive word that you wouldn't typically learn in a beginner's course.
In the lyrics, the clouds are personified: "norii din zare bârfeau de furtuni" (the clouds on the horizon were gossiping about storms). This poetic imagery is used to create a sense of impending doom, suggesting that signs of trouble in the relationship were there all along, like whispers of a coming storm.
Romanian singer Andia pairs up with rapper Deliric for "Pentru Că" (Because), and it is all about the shock of being dropped after someone promised they never would. Andia lays out the betrayal directly: the other person swore "eu nu te las" [I won't leave you], only to wipe away the clear sky with rain and break her wings mid-flight. She sings "Plutind în zbor, invers spre Pământ" [Floating in flight, backwards toward Earth], which gives this dizzying, sickening sense of falling from a great height after putting total trust in someone.
Deliric jumps in to ground that dramatic fall in everyday, messy memories. He brings up their real life together: her borrowing his oversized white T-shirt ("Un înger în tricoul meu alb" [An angel in my white T-shirt]) and complaining while cleaning the house ("făceai gură că făceai curat" [you complained/made a fuss that you were cleaning]). The phrase "a face gură" literally means "to make mouth," which is a great Romanian idiom for bickering, grumbling, or nagging loudly. But his cozy angel quickly shifts into a demon who claws at his chest and steals his oxygen. By the end, he is so bitter about the cold split that he drops the sharp punchline: "Nu cred că diavolul poate să plângă" [I don't think the devil can cry].
