完蛋

• 拼音: wán dàn
• 汉字拆解: 完 = 宀 (roof) + 元 (primary); 蛋 = 疋 (a measure/foot, phonetic) + 虫 (insect/creature) — egg, used colloquially as a mild intensifier in northern slang

含义

To be finished; done for; ruined; it's all over. Expresses total failure, collapse, or the hopeless end of something.

A vivid colloquial expression. 蛋 (egg) here is not literal — the phrase evolved into a general exclamation of total ruin, likely from the image of something as irreversibly broken as a smashed egg. Used when a person, plan, relationship, or situation has collapsed beyond saving. Can describe the speaker's own predicament (我完蛋了) or someone else's. Broadly understood but sits firmly in the casual-to-informal register — inappropriate in formal writing.

例句

2. 他把老板最重要的客户给得罪了，在这家公司算是彻底完蛋了。
