I heard of the expression "all retch and no vomit" for the first time, and the references I could find by googling it are not really clear to me. Here is the context where I found it:
What we are doing is we are bringing up children and educating them to live the same sort of lives we are living... in order that, er, that they would-may justify themselves and find satisfaction in life by bringing up their children to bring up their children to do the same things so it's all retch and no vomit — it never gets there. (Alan Watts)
What would be a definition for the expression?
