"Rack off, I'm busy!"
Where "Rack Off" Comes From
Widely believed to be a softened stand-in for a much cruder two-word phrase, with "rack" swapped in as a milder, more publicly acceptable alternative that still gets the same blunt point across.
It got a huge boost in wider recognition thanks to a famous Australian tourism campaign line — "where the bloody hell are you?" — and the character-driven comedy of shows like Kath & Kee that leaned into exactly this kind of brash local phrasing.
How Aussies Actually Use It
A blunt, no-nonsense way of telling someone to leave you alone — "rack off, I'm busy!" is direct rather than genuinely aggressive, though it's still considered a bit rude in polite company.
It's punchier than "go away" and less crude than the phrase it's often thought to be softening, making it a favourite for playful arguments as much as real ones.
