| 词汇 | killer instinct |
| 词源 | killer instinct. It is said that when former heavyweight champion Jack Dempsey fought, all he thought of was killing his opponent. In any case, the expression killer instinct seems to have been coined in the 1920s after Dempsey’s beatings of Jess Willard, Georges Carpentier, and Luis Firpo. From boxing the term was extended to all areas of life, though no major diction- ary records this very common expression. |
