Poo in a Bin, is game originating from Christchurch New Zealand, where after recent earthquakes a Barmen when cleaning up after the natural disaster found a Poo (shit, turd ass biscuit) in an empty bin out back.

from this the game "Poo in a Bin" was formed, where like similar knock and run games you have to poo in someones bin without them noticing.

shortened term is PIAB, pronounced Pie-ab
