- 1割喉式的；你死我活的（競爭）。台灣新聞講價錢戰常說「割喉戰」。
When an activity or a business is cut-throat, people are competing in an ugly way — hard, , each person trying to push the others out. Two shops may keep cutting prices until one cannot survive. At work, people may hide help so they look better. The picture behind the word is brutal: cutting someone's throat. Nobody is literally doing that; the word borrows that violence to say the contest is merciless. You hear it a lot with competition, business, industry, world: cut-throat competition is almost a set phrase, and it is never a compliment. Newspapers and business people like it because it sounds sharp. Though actually, some people write it as one word, cutthroat; the meaning does not change. It is about the fight, not about a wound on the neck.
cut-throat 用來形容競爭，表示大家爭得很難看、很狠，每個人都想把別人擠出去。例如兩家店不斷降價，直到其中一家撐不下去。在職場上，也有人會把有用的資訊藏起來，好讓自己看起來比較突出。
這個字的畫面很殘酷：割別人的喉嚨。當然沒有人真的這樣做，這個字只是借用那種暴力的感覺，說這場競爭毫不留情。它最常跟 competition、business、industry、world 這類詞搭配，像 「cut-throat competition」 幾乎是固定說法，而且從來不是稱讚的話。
報紙和商界人士很喜歡用它，因為聽起來很銳利。有人會寫成一個字 cutthroat，意思不變。這個字講的是爭鬥，不是脖子上的傷口。
組成cut + throat: a brutal picture — as if rivals would cut each other's throats — used for merciless competition.
