The original name for a soggy, smoked cigarette
butt, Australian slang from the 40's-60's.
Often misunderstood as being 'durrie', due to the way it is often slurred or mumbled at the original holder of the cigarette. People seem to repeat 'durrie' rather than 'doughie', despite 'durrie' not meaning anything.
Due to the saliva soaking into the
butt, the end of the cigarette becomes
moist, soft and like dough. Hence 'Doughie'.
