stay swiss 

To remain neutral, avoid conflict, refuse to get involved. Done when a conflict is so messy, unclear, or just flat-out retarded that it's better off just not bothering at all. The term is named after Switzerland, which has a reputation for remaining neutral. In fact, it hasn't been directly involved in a major war for over 200 years. The most recent thing close to a war was a civil war between the Catholics and Protestants that had around 100 casualties in 1847. It lasted less than a month.

Bob: Oh my god, Phil! Mark and Alice are going to war over this divorce settlement!
Phil: Sorry man, I think I'll stay Swiss.

Bob: What does that mean?
Phil: It means I don't want to be involved.
Bob: Fair enough. Fancy a beer?
