look up any word, like dog in the bathtub:
 
1.
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?"
