짬밥

jjam-bap · literally “Army mess food”

Situation: An older coworker fixes a problem in two minutes and grins: 짬밥은 못 속이지.

✕ What AI tells you

Translates it as 'You can't fool army food' or 'leftover rice doesn't lie'.

Why it fails: 짬밥 is military slang for mess-hall food. Soldiers counted service by how many meals they'd eaten, so 짬밥 came to mean experience and seniority. The coworker is saying 'Experience shows.'

✓ What Koreans actually say

짬밥 = years of experience (casual slang). Use it about yourself or among peers. With seniors, say 경력 or 연차 instead.

  • 짬밥은 못 속여요.

    jjam-ba-beun mot so-gyeo-yo

  • 제가 이 일 짬밥이 좀 돼요.

    je-ga i il jjam-ba-bi jom dwae-yo

    Casual, a little boastful: 'I've been doing this a while'

  • 경력이 오래되셨네요.

    gyeong-ryeo-gi o-rae-doe-syeon-ne-yo

    Polite way to say the same thing to a senior

  • 연차가 어떻게 되세요?

    yeon-cha-ga eo-tteo-ke doe-se-yo

    Polite way to ask how many years someone has been at the company

Cultural nuance, in depth

Because most Korean men do military service, army words leak into office talk: 짬밥, 군기 (discipline), 고참 (old hand). They sound rough and a bit macho. Telling your manager '팀장님 짬밥이 대단하시네요' sounds like you're ranking them like a fellow soldier, not showing respect. Hear it, understand it, and use it about yourself or with friends.
