Yes, there is a rule and as you see there are many exceptions or "add-on rules" in that rule.

It is not about verb or noun.

I asked that, because i smile whenever i see some kind of translations: "köpek Floss", "arı Maya", "kedi Mırnav", "inek Sarıkız"


Well, nice to hear that you dont say always "Floss Dog". If I had a dog named "Floss", i would use these words while i am talking about it(or she/he?):
"Köpeğim Floss bugün çok koştu, yoruldu."

You are welcome

Uludağ and Ilgaz are very nice for winters. There are also very good places to skiing and to see.
Good choices...

I try to find the lyrics and I will write them in the same pages with the clips, so you can follow them easily.

If I find a translation, I will add it too, so everyone can understand what the song says.

I hope you enjoy!

Ne yapıyorsun? is better.
Ne ediyorsun is also acceptable but not common. I hear that mostly in countryside, or from the people who grew up in little centers/cities or countrysides. Sometimes I use it while I am speaking with my close friends as a joke/slang:
"ne ediyon"="n'ediyon"
"n'örüyon"

By the way they can be used as a slang something like "whazzup?" or "how're you doing?" or "just "how are you?"

and in addition "what's up" and "what are the news" slangs;
"n'aber"(we know it mostly as "naber"= "ne haber")
"n'ettin"(ne yaptın=ne ettin)
But they are not for formal things, if you are very close, you can use them. Normally: Ne yapıyorsun(uz)?(+uz for mr.brown who is not close)
