그림으로 보는 오늘의 이디엄(음식 4번째)

hard to swallow : 받아들이기 힘들다

It may be a hard pill to swallow, but it is reality.

a knuckle sandwich : (주먹으로) 아가리를 한 대 침

And far better than a knuckle sandwich.

the icing on the cake , the frosting on the cake

: 빛을 더해 주는 것, 금상첨화

Positive credibility with foreign governments is frosting on the cake, not the main course of the meal.

whet your appetite : 욕구를 자극하다

However, it contains lots of reviews and pictures to whet your appetite.

a piece of cake , easy as pie , easy as abc

: 식은 죽 먹기

I'm not saying that achieving this is a piece of cake.

kill the goose that lays the golden egg

: 재산,성공 등을 가져다 줄 기회를 없애 버리다
