: "Run like the clappers.." apparently means 'flee in haste'. (I saw it in a Guardian story on volcanic lightning.) But for us old US sorts, what does 'the clappers' mean?
It has to do with the ringing of a bell.
clapper - noun [C]
a piece of metal which hangs inside a bell and makes the bell ring when it hits the sides
