Booster shot
Putting off the inevitable for as long as possible.
Procrastinating or looking for an excuse to delay making a decision or doing something necessary.
Based on the much questioned excuse used by the Western Australian premier to delay opening his state in 2022.
In that state it hit cult status quickly and became a sarcastic excuse given for apathy or to buy some time
"Sam have you finished your homework?" "No Mum I'm waiting for my booster shot haha"
"have you guys set a date yet?" "no we still aren't sure" "WTF? Are you guys waiting for a booster shot!!?"
"John any chance of you doing the rubbish this year!?" "yeh sure, soon as I get my booster shot"
"Typical tradie didn't show up!, maybe he was getting his booster shot!"
"Those doona dwellers in the hermit kingdom aren't going anywhere! Haha, cause They're waiting for their booster shots!"
