An upbeat, slightly old-fashioned goodbye, often said with a bit of cheek or posh nostalgia. You’ll hear it from aunties, shopkeepers, and anyone doing a polite exit without making a fuss. It can be genuinely warm or lightly tongue-in-cheek, like you’re tipping an imaginary hat as you head off. It’s more charming than bye and less formal than farewell.
"Right then, I’m nipping to the corner shop, cheerio. If you bump into Dave, remind him he owes me a tenner and some crisps."
