What Does 존맛탱 (Jonmattaeng / JMT) Mean?

10-Second Answer

존맛탱 (jonmattaeng), often abbreviated JMT, is internet slang meaning "insanely delicious." It's built from 존 (an intensifier, from a rougher slang root) + 맛 (taste) + 탱 (a playful ending), and it's strictly casual — food review captions and texts to friends, never formal speech.

Quick Examples

이거 완전 존맛탱!

igeo wanjeon jonmattaeng!

This is insanely delicious!

JMT ㅠㅠ 또 먹고싶다

JMT tteo meokgo sipda

So good ㅠㅠ I want to eat it again

The English-letter abbreviation JMT is extremely common in captions and comments.

Where It Sits on the Intensity Scale

PhraseIntensityRegister
맛있어요Delicious (neutral, polite)Safe anywhere
진짜 맛있어Really deliciousCasual
존맛탱 / JMTInsanely, ridiculously deliciousVery casual internet slang

존- as a prefix intensifier shows up in other slang too, and traces back to a coarser root word — 존맛탱 itself has softened into mainstream, non-vulgar usage over time, but it's still firmly informal, not something to say to a boss or write in a formal review.

Common Mistakes

Mistake #1 — Using it in formal writing or speech

It's internet/casual slang through and through — 진짜 맛있어요 is the safe formal-adjacent alternative.

Mistake #2 — Assuming JMT and 존맛탱 are different things

JMT is simply the romanized-initial shorthand for 존맛탱 — same word, faster to type.
