Bedeutung
Buying something without checking it.
Kultureller Hintergrund
In Croatian markets (pazari), it is culturally expected to touch and inspect produce before buying. Buying without checking is seen as a sign of being 'naivan' (naive). Across the Balkans, there is a general distrust of 'official' or 'packaged' goods compared to things you can see and verify yourself. This idiom is a staple of local wisdom. The rise of 'Njuškalo' (local eBay) has given this idiom a second life. It's frequently used in forum discussions about online scams. The idiom reflects a time when trade was unregulated and the burden of proof was entirely on the buyer.
Use it for 'Mystery Boxes'
If you see those 'Mystery Boxes' on Amazon, tell your Croatian friends: 'To je mačak u vreći!' They will be impressed by your idiomatic knowledge.
Check the Case
Always use 'mačka' (with an -a). If you say 'mačak', it sounds like you are literally buying a cat, not using the idiom.
