What Does Hee-eol-sa Mean? (MZ Generation Slang Guide)

Young people today are called the MZ generation, and as someone who feels a bit removed from that world, I have found that knowing a few of their slang terms really helps when having conversations with them. I am known for making an effort to connect with employees at every level, and part of that means trying to stay young at heart by learning how younger people express themselves.

1. Main Overview

When talking with younger people, I would occasionally hear words I had no idea about. These days, however, I have been making a point to look up new generation slang, and it has made it much easier to participate naturally in conversations. That is what led me to look up the meaning of "hee-eol-sa" and explore other trending slang terms along the way.

The term "hee-eol-sa" (희얼사) came up when one of my employees used it in conversation. It turns out it is a recently coined abbreviation for "hee-gwi-han eol-gul sa-jin," meaning a rare or hard-to-find photo of someone's face. It refers to photos of ordinary people or influencers (not celebrities) that are considered attractive but not widely known or shared.

2. Detailed Explanation

So when you come across a photo of someone who is good-looking but not widely recognized, you would call it a "hee-eol-sa." A related term is "hee-yeon-sa" (희연사), which stands for "hee-gwi-han yeon-ye-in sa-jin" — a rare photo of a celebrity. This refers to unreleased selfies, behind-the-scenes shots, or other photos that are not commonly seen or widely circulated.

After learning the meanings of both hee-eol-sa and hee-yeon-sa, I felt more confident that I could connect with the younger generation in conversation. This curiosity led me to explore even more slang terms.

3. How It Is Used

Another term I came across is "Meoseon-129" (머선129). This is a combination of "meoseon" (a dialect version of "what") and "129" (a pronunciation of "il-i-go," meaning "is going on"). It originated from celebrity Kang Ho-dong's distinctive accent on a variety show, where he said "moseun il-i-go" ("what is going on") in a particularly memorable way. People found it funny and started writing it as "Meoseon129" to mimic the dialect.

You can use "Meoseon129" humorously when something absurd or unexpected happens — like saying "What in the world is this?" in a lighthearted way.

4. Additional Terms

Other slang terms derived from dialect include changing the "st" sound to "st" with a softer tone — for example, "style" becomes "seutail" and "Starbucks" becomes "Seotabukseu." "Why" in the Gyeongsang dialect becomes "whyrano" (와이라노), sometimes even written in English as "whyrano."

There is also "mumul-bo" (무물보), short for "mueos-i-deun mul-eo-bo-se-yo" ("ask me anything"). It is commonly used on Instagram, where someone posts "mumul-bo" to invite followers to ask them any question they want.

5. More Slang to Know

Other abbreviation-based slang includes "nam-a-gong" (남아공), "bba-tae" (빠태), and "ju-bul" (주불). "Nam-a-gong" is short for "stay back and study" (남아서 공부나 해), "bba-tae" means a quick change of attitude or position (빠른 태세 전환), and "ju-bul" is short for "tell me your address" (주소 불러).

Seeing all these abbreviations made me wonder why young people shorten everything so much — but then I realized that my own generation had its share of shorthand too. It became a moment of understanding that every generation has its own linguistic culture.

6. Elementary School Slang

There is also "Eojjeol-TV" (어쩔티비), a term more commonly used by younger kids, including elementary schoolers. It evolved from the dismissive phrase "eojjeora-go" ("so what?") — when you do not want to respond to something annoying, you say "eojjeol-TV," as in "so what? Go watch TV."

The exact reason "TV" got attached is not entirely clear, but it carries a nuance of "whatever, go entertain yourself." After "Eojjeol-TV" caught on, variations with other appliances started appearing: "eojjeol-naengjanggo" (refrigerator), "eojjeol-notebook" (laptop), "jeojeol-geonjo-gi" (dryer), and more.

7. Sounds Like Alien Language

Another strange-sounding term is "Kukuru-ppingppong" (쿠쿠루삥뽕), also popular among younger kids, similar to "Eojjeol-TV." It does not have a deep meaning — it is used to mock or tease someone, kind of like sticking out your tongue. It is especially common in gaming contexts, where you might say it to rub in a win.

Then there is "al-jal-ttak-kkal-sen" (알잘딱깔센), short for "know it, do it well, neatly, and with sense" (알아서 잘 딱 깔끔하고 센스있게). I have actually started using this one myself when giving instructions to employees — the atmosphere lightens up and people even compliment me for staying young.

8. Encouragement Slang

When I use slang like "al-jal-ttak-kkal-sen" at work, the mood lightens and my colleagues tell me I seem youthful, which motivates me to use new slang even more often.

There is also "swip-sa-jae-bing" (쉽사재빙), used to comfort someone. It is short for "swip-ge-man sal-a-ga-myeon jae-mi-eobs-eo bingo" ("life is no fun if it is too easy, bingo"), which comes from lyrics by the Korean singer Geobukkie. Slang derived from song lyrics like this often resonates across generations and helps build a sense of shared culture.

9. YouTube Culture Slang

Another widely used expression is "joh-daet-gu-al" (좋댓구알), which stands for like, comment, subscribe, and turn on notifications (좋아요, 댓글, 구독, 알림설정). As more people launch their own YouTube channels, creators use this phrase to ask viewers to engage with their content. It has become a standard sign-off expression for YouTube creators looking to build a stronger connection with their audience.

Starting from "hee-eol-sa," I have now explored a whole range of slang terms, and I am genuinely curious about what clever new expressions will emerge next.

10. Closing Thoughts

I plan to keep learning new slang so I can stay closer to the younger people around me. I believe this kind of effort plays an important role in bridging the generational gap in communication.

If you work with young people or have teenage children at home, I encourage you to pick up a few of these expressions and try using them — you might be surprised by the positive reaction you get. Understanding and appropriately using generational slang is one of the most effective ways to break down barriers between generations.
