Kur does not mean rooster. It means cock both literally and figuratively.
Its preserved in its original, non-offensive meaning in words like “kurnik” (chickencoop), but otherwise it’s used almost exclusively for B=================
@”Kapitán Denis” if you have “kura”, it means you had kur, too. Lol
Also, everyone has “kurva”. Ton of them, in fact.
Another thing – in Serbian they use “kurac”, which is diminutive of “kur”. No idea whether this is modesty or objective assessment.
