A large black bin which sits outside pretty much every house in Australia. It's sole purpose is for rubbish which is collected every week by the rubbish colection, but the wheelie bin is used for many other things. Probably the most fun is the practice of getting so unimaginably drunk that you can't stand and have to be wheeled home in one of these bins.
"Oh shit man - He's maggot! Time for the wheelie bin!"
