Humorous slang, primarily Australian in usage, meaning to break wind or pass gas. The phrase leans into the blunt, irreverent style of Aussie colloquial speech, finding comedy in the most everyday of bodily functions. Like many Antipodean euphemisms for flatulence, it's more likely to generate a laugh than genuine offence, deployed in casual conversation to take the edge off an awkward moment or to describe someone else's antisocial contribution to the room's atmosphere.
He tried to crack a rat quietly during the meeting but the silence made it worse for everyone.
