My exposure to Swiss German has still only been cursory..but I am in Bavaria with equally interesting language stylings. I have to ask my non-Bavarian friends to keep my German in check, so I know when a local phrase slipped into the Hochdeutsch.

I still have to remind myself to be careful saying "ein bissl" or "es passt schon" outside of Bavaria. Those phrases combined with my lederhosen and Filzhut would give me away as living in the South.
