A friend of mine asked me a very good question and that were the origins of the term "crni ti" whenever they share a hardship they're dealing with to their friends.
I wasn't sure how to answer this since I don't know the origins myself and judging from some Google searches it seems to be a unique thing for the people of the Western Balkans (Serbo-Croatian to be more precise).
Does this community have any historical context of the origins of this term?
