an aussie slang term for the those cheap 4 liter wine containers. Due to the excessive drinking in the aboriginal territories and the silver plastic bag inside the carton
the term goonbag evolved.
"... come on everyone throw in a dollar, let´s get a goonbag."
a term that means absolutely nothing. it is most commonly used in a situation where someone does not know what to say. "goongaga" is almost always placed after the words "me" or "you"
