Not sure if this is in the right place, but I thought Pedants' Corner would reach the people interested in words and phrases.
Have you ever come across the phrase above? It was used by my parents but I think came from my mother rather than father. She was brought up on the Wirral, dad was from Kent.
I (and other family members) have tried and failed to find it used anywhere other than our family but it struck me that this would be a good wide pool of people to ask.
For me it means dithering about, trying to put off what you should be doing - usually as a child related to going to bed...
"What are you doing still down here?"
"I just wanted a glass of water."
"Stop hanging the latch and get to bed!"
Have you ever heard it? And if not, would you be able to take a guess at its meaning? I suppose in context as above it's reasonably clear.
