Kif int, Victor? :) I am 100% sure that the authors of these Kazakh sentences are Kazakhs from Turkey. The meaning: "Do you study in Kazan University?" "No, I am studying/reading in black kazan." Victor, if you speak Russian, you know the other meaning of the word "kazan" (without мягкий знак), where you can cook something. This kind of joke is used by Kazan Tatars, e.g. "How is the weather in Kazan?" - "Kazan is boiling" :) So, city Kazan and kazan for cooking meal. There is no idioms here!

" Do you study in Kazan University? No, I'm studying in Kara Kazan" ,it's correct.. Kara Kazan,may be means I study by myself

" Do you study in Kazan University? No, I'm studying in Kara Kazan" ,it's correct.. Kara Kazan,may be means I study by myself

I think: Mr.A: Are you Kazan univ student? Mr.B: No I am a idler. "Qara qazan" probably idiom. Sometimes some people dont like talk straight. In this case use idiom. It depend situation.

I'm not a Kazak, my friend but a Turkey Turk yet i can say what i understand. Do you study in Kazan University? No, I'm studying in Kara Kazan.
