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?"

When you have balls the size of church bells to post something on Facebook that will literally piss off 8 out of 10 of your friends such that most of them unfriend you as a result.
Mich: OMG did you see Phil's post on Facebook? He literally said no wonder we are a country full of P's responding to all the democrats crying that Hillary lost to Trump. Now that's FB sack!

When your scrotal sack sticks to each side of inner thighsl usually due to long term sitting or swass and when you stand up it resembles the full sails of the Black Pearl.
"Man, I was working in the office all day and when I got up my sail sack had me thinking of my next vacation."
