Argentine slang of relatively recent invention, purportedly meaning commercial operations that are kept unregistered to elude sales taxes. There's been a recent push to impose this word, via twitter and other social media flame wars. According to the pushing party it comes from a small community of originally Syrian Jewish merchants of Buenos Aires. A dubious Arabic or Turkish origin is claimed for this term, which is nonetheless not in use, with such meaning, either in colloquial or grammatical Arabic or Turkish. There's an Arabic term matching the word and meaning "external, extraneous, exterior, foreign." Used in US as well
"¿La venta es en blanco o en barrani?"
* Only one "like" per meaning and day, the more "likes" the meaning will appear higher in the list
