FAQ
Frequently Asked Questions
It is not a traditional swear word (obscenity), but it is a very rude and forceful command, on par with 'piss off'. It can be offensive.
You might be understood by some, but it will likely mark you as an Australian/NZ speaker or someone using unfamiliar slang. It's better to use more universally understood alternatives like 'get lost' or 'go away'.
Both mean 'go away'. 'Rack off' is stronger, more abrupt, and regionally specific (Australasia). 'Push off' is milder, older, and more associated with British English.
The etymology is uncertain. It may derive from 'rack' meaning to stretch or strain (i.e., to stretch oneself away), or from 'wrack' (as in wreck). Its documented use is primarily 20th-century Australian.
