Wonkey Donkey Billy Bongey

When you find some manky ass billy at the side of a park hidden in some bushes made out of a texta, a gatorade bottle and a bit of a coke can as a pc and you and your mate have nothing else to do so you have a few cones with some low grade bud.

ur mate: OH FUK YEAH!!! LETS USE IT!!!!
