게 깨지다

break; also, get thrashed

깨지다 is something breaking — glass that breaks easily, a forehead split open. It also means being beaten badly or torn into, which is what 작살나게 깨졌다 means. Of a number it is a level giving way, as with the three trillion mark, and of money 돈이 깨지다 is a serious chunk going out. The -게 slot gives the manner or the degree.

Register: everyday; slangy in the 'thrashed' sense
