What's "Cor" mean

> it means "Wow", something that is really good and unexpected. I'm not sure of the 
derivation but I had always thought it was one of those expressions that didn't really start out 
as a word but is written as "Cor". Similar to "Ugh" I suppose.  However if anyone DOES know 
its derivation (Carol??) I love to know as well.

Pippin:
It's supposed to be a corruption of "Gore blimey" which is in turn a corruption 
of "God blind me." It's an expression of surprise or wonder. I think it's still in use.
