Literal translation
to chat like a one-eyed prostitute
Meaning
to talk a great deal, and mostly nonsense
Explanation
The verb blaga means to chat, to talk freely and at length, while puto borgno pairs the prostitute, a stock figure of street gossip in folk speech, with the impairment of partial blindness, suggesting here poor judgment as much as a physical defect. The image thus combines two traits that together sketch someone who talks a great deal without discernment, unable to gauge the relevance or accuracy of what they say, much as a half-blind eye only perceives part of reality. The expression, both crude and vivid, belongs to a distinctly coarse register and should be handled with care, kept for very familiar exchanges among close acquaintances, well outside any formal setting. It is used to mock someone who talks a lot, often with little substance, stressing the disjointed, unreliable nature of their words far more than their sheer volume.
