Everyone's Saying 'Yareu'—An Old Catchphrase Making a Comeback?

Have you heard someone shout 'Yareu!' after receiving good news? It may sound like a secret code, but think of it as an excited 'Yes!' or 'Woo-hoo!' used when you feel great. The little word comes with a surprise, though: what seems like a brand-new expression was apparently heard on a drama set years ago.

This week's buzz is about finding the 'original'

On October 21, 2026, Sports Kyunghyang and Xportsnews reported on reactions to 'yareu' featured on actress Lee Min-jung's YouTube channel. According to the reports, a behind-the-scenes video from the 2009 KBS2 drama Boys Over Flowers showing Lee using the word began attracting attention again. That's an example from 17 years earlier.

More interesting was Lee's own explanation. She said the phrase was not something she invented herself, but one she and her friends had used long ago. It's fun to discover someone's familiar expression in an old video, but that does not automatically make the person its original creator.

It did not suddenly appear this week

Broadcast records take the timeline further back than this week's buzz. An iMBC Entertainment preview of Radio Star published on May 20, 2026, described Kim Chang-wan using 'yareu' as a word he had learned recently, and Roy Kim explaining it as an interjection used when excited. So it had been discussed on television since at least this spring, rather than appearing for the first time this week.

It's more accurate to view today's trend as the rediscovery of a familiar expression than the birth of an entirely new word. Still, the materials reviewed do not establish who first used it or its exact etymology. An old clip proves the expression was used at that time, not that it was coined on that day.

Try it for small happy moments

To get the feel of the word, think of ordinary little pleasures rather than memorizing a big new slang term. The following are examples written by Jumak to illustrate its use, not quotations from real posts: 'The last dumpling at lunch is mine—yareu!' or 'I finally finished all my overdue work. Yareu!' Just add it after something good happens.

Tone matters, though. According to Xportsnews, Lee's explanation included not only excitement but also a sense of triumph or playful teasing. If you're trying it for the first time, expressing your own delight is safer than saying it about someone else's mistake. To a friend who doesn't know the word, simply explain, 'It means I'm happy!'

More fun than new slang is laughing together

For some, it's a newly learned interjection; for others, a phrase they used with friends years ago. Simply asking 'You know this one too?' can bring back different memories. Rather than drawing lines between people who know the latest expressions and those who don't, why not enjoy the different ways we remember the same words?

If something small and good happens today, give 'yareu' a try. There's no need to memorize it just to keep up with trends. When a funny word becomes part of your own way of speaking, even a brief exclamation can change the mood of a conversation.
