I learnt a new word today that I think is worthy of sharing:

Spiesser

It wasn't applied to me incidentally, but I think I that may have cause to use it...

I think the Swiss-German is Bünzli...

yep, this came up at lunch the other day & is aparently quite insulting ... needless to say, was immediately locked away in my portable data bank for future use ...

Spiessbürger works as well.

Or "Füdlibürger" for that matter.. I especially like this one because of its lovely connotations

Spiesser is less insulting than Spiessbürger and Bünzli, and Füdlibürger is more - You want to get the order right for a cultivated, escalating exchange of compliments

Black Adder refers.

What is the opposite ? It would be "bohemian" in English.

I have a few ideas, but I am not a native speaker.

The first thing that came into mind was "der Hippie" and the Swiss missus (she's already posted in here earlier) came up with that word as well. I guess you could use "der Beatnik" or "der Antikonformist." Anybody else?

I think that Bohemian has a slightly different context in German because of Bohemia (Böhmen). Ok, it looks like both Bohemien and Boheme work.

My best guess is "Bohemien" as it is spelled in French but it's rarely used. Other possibilities that are somewhat more common:
Nonkonfirmist
Freigeist, Freidenker (free thinker)

Not exact matches for bohemian but also implying open-mindedness:
Weltbürger (cosmopolitan)
Avantgardist

You know that Spiess means spear in German, right? So a Spiessbürger is a citizen with a spear in his hand.

Oops. Bohemien as it is pronounced in French. I'm sorry, I'm used to forums with edit option!
Why are half of our expressions for open-mindedness of French origin, anyway?

Lebenskünstler?
