Yes, people do drink beer — or really any beverage — out of a shoe. Doing that is called a “shoey” and, well, some people love it, some people think it’s disgusting. In saying that, it’s a teenage ritual that almost every Australian completes. You never forget your first shoey.
As for wine bags, you have to call it what we do — goon. Goon is love, goon is life and all you Americans must visit Australia so we can play goon of fortune (look it up, I dare you).
And yeah, we do use red solo cups, or just ordinary cups. I do counter that and say — what’s with the red solo cup obsession?
