danımarkalı bı hatunla tanıstım

 I have met a Dannish [a woman /girl from Denmark] woman .

"hatun" is a slang word for "woman, girl "

Thank you very much. When and who does usally use the word hatun?

 You are welcome Arlinda. Actually , as I said it s a slang word , it s used among guys [men] .Its like " chick ", or " bird " , " baby"

Good to know, then I won´t use it myself! 

Actually it is not always slang. But young people use it that way. Hatun means wife, queen. Actually it is a foreign word. And it comes from Sogdian language according to Sevan Nişanyan.
