Where "Uey" Comes From
"Uey" is simply Aussie shorthand for a U-turn — the letter U, said out loud, with the classic Australian "-ey/-ie" suffix that turns nouns and verbs into familiar, informal versions of themselves: arvo (afternoon), servo (service station), rego (registration). The earliest uses of "uey" in this sense date from the early 1970s, and it pairs naturally with "chuck" — another all-purpose Aussie verb — to give the full phrase "chuck a uey."
"Chuck a uey" is part of a broader family of "chuck a..." expressions in Australian English: chuck a sickie (take a fake sick day), chuck a wobbly (have a tantrum), chuck a snag on the barbie. All of them use "chuck" in the sense of "perform a specific action," making it one of the most generative verbs in the Australian slang vocabulary.
"Chuck a uey at the servo, we missed the turn."
How Aussies Actually Use It
"Chuck a uey" is almost exclusively used behind the wheel — missing a turn, needing to backtrack, or just deciding to head somewhere else entirely. It's casual and instantly understood by any Australian driver.
It can also be used more loosely to describe changing your mind or reversing a decision, similar to "doing a 180," though the driving sense is by far the most common.
