Collecting together money from your pockets, bag,
around the house or down the back of the settee. Usually collected together to buy some small item like a pint of milk or a loaf of sliced bread. Therefore all the pennies and
small change in copper will have an inordinate value.
May be used as a slightly offensive word if you have a group of people pooling all their money to buy a cheap bottle of wine between them or some similar
object of desire.
