Kosher as 'okay' or 'clean'

I don't see any reason why the word 'kosher' would need to refer only to food. Jess may have been the one who introduced me to using the word for a variety of things. It means that something is good, or clean, or acceptable. Or it can mean content -- i.e. "Would you like some more water?" -- "Naw, I'm kosh."

Anyhow, I was very pleased when I opened up Today's Papers on Slate this morning. The headline? "Iran's Guardian Council: Election Was Kosher."
