[Opinions] Re: can i use the name trifko?
It's OK to use it if you like it that much. It is pleasing; I know quite a lot about Franz Ferdinand's death and its consequences, but I don't remember having seen Trifko before, though I surely must have. So, don't worry that everyone will make the connection. Or, perhaps feminise it and become Trifka: depending on your personal gender, of course.
