K’vo? (к’во?)

This is a shortened version of kakvo (какво) which means ‘what’ and is generally used as a way of saying ‘pardon’. In terms of slang, k’vo? is one step further on from that - the equivalent of saying ‘wha?’ to someone. It’s practically the only thing I can say with an authentic sounding accent and, because it’s so colloquial, it’s pretty much guaranteed to get an easy laugh from native Bulgarians when someone says something I don’t understand. I once forgot myself on a plane and said it to a posh elderly woman which didn’t go down quite so well.
