Quoting sevimli

(NAME) gardasim sen yaramaz adamsin den can

I think can may be a name

Thanks for your help 

It is not so clear, so this may have different meanings:

(Name) brother, you are a naughty man, Can.

(Name) brother, you are a useless man, Can.

If Can is not a name it may also mean ´dear´.

I think it probably means useless!!!!

Thanks for your help
