Korean Slang: 플렉스 / 드립 (Peullekseu / Deurip)

"Flex (show off spending) / Joke/Quip" — Modern Korean slang you need to know.

The Slang

플렉스 / 드립 (Peullekseu / Deurip) — "Flex (show off spending) / Joke/Quip" 플렉스 from English 'flex.' 드립 from '애드리브' (ad-lib), meaning a witty remark. This is the kind of Korean you won't find in textbooks but will encounter everywhere online — in comments, texts, and social media. Understanding modern slang is key to sounding natural.

Why English Speakers Get It Wrong

Korean slang evolves fast and often uses abbreviations, wordplay, or borrowed English in unexpected ways. 플렉스 / 드립 might look unfamiliar even if you know standard Korean. The challenge isn't just vocabulary — it's keeping up with how young Koreans actually communicate. Textbook Korean and real-life Korean are different worlds.

How It Works

Usage: 플렉스 when flaunting purchases. 드립 for clever jokes or wordplay. Examples: • 플렉스 좀 했어. (peurrekseu jom haeteo.) — "I flexed a bit. (splurged)" • 그 드립 재밌다 ㅋㅋ (geu deurip jaemitda ㅋㅋ) — "That joke is funny lol" You'll see this in Korean YouTube comments, KakaoTalk messages, and social media posts.

Real Examples

• 플렉스 좀 했어. (peurrekseu jom haeteo.) — "I flexed a bit. (splurged)" • 그 드립 재밌다 ㅋㅋ (geu deurip jaemitda ㅋㅋ) — "That joke is funny lol"

Common Mistakes

❌ Using slang in formal situations (work, elders, strangers) ✅ 플렉스 / 드립 is for casual contexts: friends, texts, social media → Korean has strict formality levels. Using slang with your boss or professor is a serious social mistake. ❌ Overusing slang as a foreigner ✅ Start with understanding, then gradually use it when comfortable → Koreans appreciate when foreigners understand slang, but overuse can sound unnatural.
