자며

'You said let's…, didn't you?'

-자며 throws a proposal back at whoever made it, usually as a complaint that they have gone back on it: 야! 네가 15개 걸자며 'you were the one saying to bet 15!' Several lines here are on-screen captions calling someone out. The same form also just quotes a proposal inside a longer sentence — 10년 뒤에 이곳에서 만나자며 'saying they'd meet here in ten years' — with no accusation.

Register: casual, accusing
