芭比Q is a phonetic rendering of 'barbecue.' It went viral from a Douyin (TikTok) video where someone said '完了，芭比Q了' while something caught fire. It means 'it's over / we're cooked' - similar to the English slang 'we're cooked.'
usage
Always used humorously to express doom or failure. The 了 at the end is essential - 芭比Q了 is the complete phrase. Very popular with younger Chinese internet users (Gen Z).
