Actually Spoken by Koreans

A hyper-diligent, self-improving life — early rising, exercise, study, no wasted time. From 'God' + 生 'life'.

An unspoken default everyone just follows — the national rule of Korean life. Used as ○○은 국룰.

'Back in my day' — reminiscing about the past or stressing how tough your generation had it

An iced-coffee die-hard — someone who orders iced americano no matter how freezing it is outside.

'Today's workout, done' — a check-in tag posted after finishing a daily workout.
