good in the sack

When you're good in bed. You got them off and actually did your part unlike someone who just laid there. A guy might call you good in the sack if you were kinky and into trying things as well.

"Jane is really good in the sack."

goon sack

The name given to wine, generally white, when removed from the cask. The sack is made of a strong foil, so it can be passed around without getting damaged.
It is a popular alcohol choice for Australian teenagers, as it costs no more than $15 for 4 litres, which is a very affordable way to get fucked up.
When one is intoxicated, they often drink the juice straight from the sack, although it is also commonly mixed with other liquids such as orange juice or soft drink, to make the taste more tolerable.

girl "Hey, pass the goon sack."
boy "Ok, do you want a cup, too?"
girl "Are you serious? I have it straight from the sack."

get the sack

Getting fired from your job. Australians use this phrase a lot. Probably from the pioneer days when the boss would throw a bag at the farmhand/miner/builder/labourer's head, tell him to pack his stuff and get lost.

"Bloody hell, the boss gave me the sack!"

"Are you going to get the sack for skipping work yesterday?"
