I am, really and truly, not kidding about this.
In reading your reply, however, S'sHBG, I feel compelled to point something out: I too, as it happens, am Bohemian. Why do I capitalize the "B" you ask? Simple- I'm using it as a proper noun, not an adjective. My grandmother immigrated to the United States with her parents and siblings when she was just a little girl. As you may have guessed, they immigrated from Bohemia. (For those who don't know, Bohemia is a region in the Czech Republic) When she grew up, she married a man who was born here in the states, but both of whose parents were Bohemian. My grandparents both spoke Czech (Which was a source of constant amusement. When we were little, my grandparents would keep things from my sister and I by discussing them in Czech. One of these things was the possibility of a trip to the local playground, named "Kiddie Park." It would appear, however, that there is no Czech equivalent for "Kiddie Park" and thus they would simply insert the English words into their otherwise unintelligible dialogue. Whether this was a consequence of absentmindedness, or a desire to whip us into a frenzy, I do not choose to speculate on) and passed on a considerable amount of Bohemian culture (And, thankfully, quisine) to my mother, who you will note is also full-blood Bohemian.
Now, my mother did not marry another Bohemian (A source of some consternation for my grandparents, however briefly) but nevertheless, all this means that I am half-blood Bohemian.
So, no offense, but I'm pretty sure my Bohemian trumps your friends' bohemian.
