look up any word, like porb:
 
1.
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.
Peter Stringfellow (The king of strip clubs) said recently 'The worst customers we have in here are groups of women (hen parties). They are always coppering together to buy one male stripper between them'.
