A "rack" was a slang term for a motor-bike for older Australians. So, to go get "on-yer-bike" and go away upon a command you would be "racking off". To rack off is less rude, but alliterative, for another popular expression.
Hello mate, may i come to your party and dance the "Maroubra Stomp?"
No, mate, you may not. Rack Off.
This is a phrase used in the absence of the phrases such as fuck off or piss off. It can be said to people of older generations and they cannot tell you off as they dont know what it means.
It is also used when a person cant be arsed to have an argument but knows hes right;
Person 1 - your such a gay bastard, why did u put ur head in my crotch.
This is a word not really used in the English language. I know this word because my English teacher is Australian and she thought us a lesson on Australian slang and rack off means go away. It may ounce ruder then saying go away but it is not rude at all and Harry I love u loads babes!!!❤️❤️❤️💜💜💜❤️💜❤️💜❤️💜
Australian term popular in the 70's and rarely heard now. Not without it's peculiar Oz charm and used in a fairly benign manner to tell some charmless, or possibly, devilishly charming lair to get a move on.
At the local, a boyishly handsome wag is eyeing up the pretty barmaid.
He not so subtly makes it clear to his mates that she is rather attractive, and completely at his mercy.
Wag: Patty has splendid breast definition, wouldn't you agree?
Sniggering round of agreement from assembled uglies.
Patty: Oh, Rack off Normie! You and your mates!
Giggles all round from the ladies, and rounds of applause from the gents.
