Definition of goon ?

Goon is cheap wine in a box—the official fuel of broke backpackers and chaotic uni students. It’s not classy, but it gets the job done, usually too well. Comes in a silver bag that doubles as a pillow after your life decisions catch up with you. Aussies have a weird love-hate relationship with goon: we roast it constantly, but somehow it ends up at every party. If someone offers you goon, you’re either about to make a new best friend or deeply regret tomorrow.

Only bogans and backpackers smash goon like that.
