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.

It is used to mean the best of the best by adding the Chinese character 'Wang' (王) to the English word 'King' and adding 'Jjang' (meaning best). It was discovered during the 'Finding Idiot IDs' event on the DC Inside World of Warcraft (WOW) Gallery and was soon selected by the gallery members as the 'most powerful ID'.

A derogatory term for someone obsessively devoted to something or someone — especially a celebrity — to the point of making other people uncomfortable. Male super-fans are called "ppa-dori," female ones "ppa-suni." The opposite, someone fixated on hating a target, is a "kka."

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

"American TV drama," shortened.

Used similarly to "nakshi" (bait/clickbait). Before this term caught on, "nakshi" was more common, but it overtook it in popularity after a viral meme of a Black man holding a Yu-Gi-Oh card saying "You've activated my trap card!" It's also used in the fuller form "trap card."
