This is the milk man who is selling Milk and Matsoni on the streets of Old Tbilisi. He is screaming “Moloko, Matsoni!”
There are women who sell raspberries (“malina”) on the streets every morning, and they make their presence known by screaming “malina, malinaaa” at the top of their lungs, with the most painful inflection.
Also, there are “Jarti” guys – “JARTS VIBAREB JAARTS!! SARECKHIS MANQANAS, KONDICIONERS, MACIVARS!!”. These guys show up once a month in an old Lady and buy out old scrap metal from the locals. However, their car looks like it’s itself is up to be sold for the scrap metal.
In some neighborhoods of Tbilisi, locals wake up to “BOTLEBS VIBAREB BOTLEEEEBS”. This means that someone is up to buy empty bottles.
Some other loud keywords can be heard in Tbilisi markets. Sellers seek attention the old school way.
