A trainwreck is something — or someone — that has gone wrong so completely that it is almost impressive. The literal meaning is a train crash, and the figure of speech keeps the whole scene: something large, moving fast, that cannot be stopped, and that people cannot stop staring at either.

A trainwreck is something — or someone —trainwreck指的是某件事——或某個人—— that has gone wrong so completely搞砸到一個地步 that it is almost impressive反而讓人覺得誇張到有點厲害. The literal meaning is a train crash字面意思是火車出軌, and the figure of speech keeps the whole scene這個比喻保留了整個畫面: something large, moving fast某個龐大、快速前進的東西, that cannot be stopped停不下來, and that people cannot stop staring at either而且大家也沒辦法別過頭不看.

So a job interview that goes badly from the first question is a trainwreck; a company launch where nothing works is a trainwreck; a film with a confused story and bad acting is a trainwreck. Used of a person, it means someone whose life is visibly falling apart — money, relationships, health all going wrong at once.

So所以, a job interview that goes badly from the first question一開始就出包的面試 is a trainwreck是個trainwreck; a company launch where nothing works什麼都出錯的公司發表會 is a trainwreck是個trainwreck; a film with a confused story and bad acting劇情混亂、演技又差的電影 is a trainwreck也是個trainwreck.

That use is harsh and can be cruel, so be careful: it is fine about yourself ("I was a complete trainwreck that year") and fine about a public figure in a joking way, but said about a friend or a colleague it is an insult. There is also a common phrase, watching a trainwreck in slow motion, for seeing a disaster coming and being unable to look away or to stop it.

That use is harsh and can be cruel這種用法很尖銳，甚至可能很殘忍, so be careful所以要小心: it is fine about yourself講自己沒問題 ("I was a complete trainwreck that year""I was a complete trainwreck that year"那年我整個人一團糟) and fine about a public figure in a joking way開玩笑講公眾人物也沒問題, but said about a friend or a colleague但拿來說朋友或同事 it is an insult就是一種侮辱. There is also a common phrase還有一個常見的說法, watching a trainwreck in slow motionwatching a trainwreck in slow motion（慢動作看著一場災難發生）, for seeing a disaster coming指的是看著災難逼近 and being unable to look away or to stop it卻沒辦法別開視線，也沒辦法阻止它.

The word is informal and modern, at home in conversation, social media, and reviews, and out of place in a business report or an essay. You will see it written three ways — trainwreck, train wreck, train-wreck — with the two-word form more usual in American writing; all are accepted.
