Word of the week - boh

In view of my recent trip, this week we travel to Italy to find our word of the week. Boh is a bit rude and means I don't know or I don't care and although I couldn't find it in my dictionary it does appear in the BBC's language website under "cool Italian" click here to hear it pronounced, where it says it is usually accompanied by a shrug of the shoulders. When I first encountered it I was impressed by the level of laziness it conveys.

Che ora e?

What time is it?

Boh!

How the hell should I know!
