What does 플렉스 (peullekseu) mean? How Korea borrowed “flex” from hip-hop
플렉스 (peullekseu) means showing off by spending money or flaunting what you have. It came over from American hip-hop and blew up in Korea in 2019, the same year a survey found people in their 20s were buying about 7.5 times as many luxury goods as two years earlier.
At a glance
- Meaning
- Showing off by spending money or flaunting what you own or have done. Used as 플렉스하다 (to flex) or 플렉스 해버렸다 (went and flexed).
- Origin
- The English “flex” (to bend, to tense a muscle) came to mean flaunting wealth in American hip-hop, and arrived in Korea with that meaning (Maeil Shinmun, Dailian).
- Spread
- In 2019 rapper Yumdda's line “플렉스 해버렸지 뭐야” (“oops, I flexed”) spread across TV and social media.
- In English
- Same word, same meaning. Overdo it and you get “weird flex but ok.”
The day after getting his allowance, a grandson shows up at his grandmother's in brand-new sneakers. She looks at the shoes; he looks at his phone. The characters are invented, but every fact in their conversation has a source.
What does 플렉스 (peullekseu) mean? A grandson explains to his grandma
- Grandma (72)Those shoes are blinding. How much were they?
- Do-yoon (19)I saved up my allowance and did a little 플렉스.
- Grandma (72)플렉스? Isn't that an exercise? Bending your arm?
- Do-yoon (19)Half right. The English “flex” originally means to bend, or tense a muscle. A Maeil Shinmun article says the slang grew out of that.
- Grandma (72)So instead of muscles you're showing off what?
- Do-yoon (19)Money. It's how American rappers talked about flaunting wealth, and it came over as is. Dailian also says it's from hip-hop.
- Grandma (72)So in plain Korean, bragging about money.
- Do-yoon (19)Yep. In 2019 the rapper Yumdda showed off luxury stuff and said “플렉스 해버렸지 뭐야,” and it went everywhere. Wikitree says that March he sold T-shirts and made about 60 million won in four days.
- Grandma (72)60 million from T-shirts? Maybe I should sell my knitting.
- Do-yoon (19)That year people in their 20s were buying about 7.5 times as many luxury items as two years earlier. That's a Lotte Members report, and the top item was sneakers, at 27.7%.
- Grandma (72)So that's what's on your feet. Who said it first, though?
- Do-yoon (19)Nobody's sure. The articles agree it came from American hip-hop, but who first used it in Korea isn't known.
- Grandma (72)Then let your grandma try. Tonight I'm doing a beef 플렉스.
플렉스
Showing off by spending money or flaunting what you own or have achieved. From the English “flex”; also used as a verb, 플렉스하다 or 플렉스 해버렸다.
In Korean: 돈을 쓰거나 가진 것, 이룬 것을 자랑하며 과시하는 것. 영어 flex에서 왔고, '플렉스하다', '플렉스 해버렸다'처럼 동사로도 쓴다.
- 첫 월급 받은 기념으로 부모님께 한우 플렉스 했어Got my first paycheck, so I did a Korean-beef 플렉스 for my parents.A proud photo one month into the job
- 택시 탈까 말까 고민하다가 그냥 플렉스 해버렸지 뭐야Couldn't decide on a taxi, so oops, I just went and 플렉스'd.1 a.m., after the last bus
- 이번 달은 플렉스 금지야. 카드 명세서가 무서워No 플렉스 this month. My card statement scares me.An end-of-month resolution
- 전교 1등 했다고 플렉스하는 건 좀 귀엽다Him flexing about being top of the school is kind of cute.Siblings' group chat
Why did 플렉스 catch on in Korea?
Bragging is normally awkward. 플렉스 wraps it in hip-hop swagger and a joke. “I bragged about money” is embarrassing; “oops, I flexed” you can say with a grin. As Maeil Shinmun noted, it settled in as the casual caption for an expensive purchase on social media, and it scales freely: beef is a flex, a taxi is a flex, a buy-one-get-one at the convenience store is a flex. For the bank balance afterward, see 텅장 (teongjang, “empty account”); for reviews of things you paid for yourself, see 내돈내산 (naedonnaesan).

Q. Where does 플렉스 come from?

Yes. In English slang, “flex” also means to show off. An awkward boast earns a “weird flex but ok.”

So 플렉스 is an English word for tensing your muscles that became a Korean word for tensing your wallet. Do-yoon's grandmother really did buy beef that night. Whether she said “플렉스 해버렸지 뭐야” at the checkout is unconfirmed. And if you have a sharper definition, add it to the 플렉스 entry in the dictionary.
