I recently used the term “chockers” meaning very full, almost overflowing. It seems to be common usage where I live (Australia) as everyone seems to understand it. But what is its origin? My husband told me that his family said it came from a particular type of chocolate bar popular in the late 1940’s that was advertised as a “Choco Block - Full of Chocolate” and hence became firs the term, chockoblock, then shortened to chockers.
Is this true, or ist there another explanation.
