Slang, explained by the people who actually use it.

명사 "꿀"과 "재미"를 줄인 "잼"의 합성어. '완전 재밌다'는 뜻이다.

Originally from a polite gamer sign-off ("enjoy the game"), it got shortened over time and repurposed to mean "forget it" or "get lost" — often used to shut down an absurd item-trade offer or dismiss someone outright.

A suffix shortened from "-grade student" — used as "yu-ding" (kindergartner), "cho-ding" (elementary schooler), "jung-ding" (middle schooler), "go-ding" (high schooler), "dae-ding" (college student), "jik-ding" (office worker). As youth crime has risen, harsher, more contemptuous versions aimed at middle/high schoolers have become more common than the plain forms.

Originally short for "you won't get a girlfriend" (an-saenggyeoyo). On the far-right forum Ilbe, it took on a mocking tone, sometimes paired with a faux-dialect phrase implying "things weren't like this in the old days."

From the sound of heavy, moaning breath during sexual arousal — used when looking at sexually suggestive photos or videos.

"There's no getting out of it/denying it, can't" (mixing Korean with English "can't") — you're stuck, no way around it.

Tied to English football club Leeds United, who were a Premier League force around 2000 before financial trouble sent them tumbling to the third division. "Your Leeds days" (your peak) is now used generally to mean someone's glory days or prime.

Used jokingly to brush off a demand for a logical explanation. Carries a misogynistic undertone, implying "when conflict arises, women irresponsibly play dumb and only act cute when it's convenient" — its use is controversial for that reason.
