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.

"Me" + "economy" — spending centred on yourself and what you enjoy.

A moment worth posting on Instagram.

"Honey" (kkul) plus a shortened "fun" (jaem) — means "a great time, really fun."

Short for "alone at a coin karaoke" — going by yourself to a coin-operated karaoke booth to sing.

Someone who lectures others and forces their own way of doing things. Originally meant an older person, now used for anyone who acts that way.
