Australian crude slang meaning to defecate, with the sense of cautiously extruding or 'reversing out' a bowel movement. The phrasing has a deliberately absurd vehicular metaphor — 'backing out' as you would a car — which is typical of Australian earthy humour. Used in casual blokey conversation and comedy contexts. The phrase is blunt but more comic than aggressive in register, and it lands as a knowing joke rather than a shock term.
He'd eaten a whole pack of Tim Tams and announced he needed to go back one out before they got back in the car.

Australian slang for defecating, using the spatial metaphor of backing a vehicle out of a space. Somewhat euphemistic compared to more direct terms, but the vehicle imagery makes it simultaneously vivid and deniable. Casual in register and typically used among friends rather than in polite or mixed company. A characteristic example of Australian slang's preference for unexpected metaphors. The slang falls into the Australian tradition of applying mundane mechanical metaphors to bodily functions for deadpan comic effect.
He told the group he'd be five minutes — he needed to back one out before they left.
