Similar to the "One night stand" or "Booty Call"
Aussie slang for - To have sex with, and then kick out straight after
So, in essence - Hooking up with someone for one night of sex with no strings attached and hoping to never see them again.

Do not exchange personal info as this defeats the purpose of the good ol' root n boot
