hothead

性急的人；鲁莽的人英释中释nsomeone who does things too quickly without thinking

1 Like all tension tamers, the coffee buddy has good timing. When office stress hits its peak, he knows the hothead to take out of the office..就像其他缓解紧张的高手一样，咖啡密友也能够掌握绝佳的时机。当办公室压力高涨到顶峰的时候，他就知道该让办公室里性急的人出去透透气了。

2 He already had a reputation for being a bit rash and a bit of a hothead, and I fully expected his colleagues to write him off as a complete lunatic..他本来就因为鲁莽和急躁出名，我完全可以想象他的同事们把他当成一个不可救药的疯子。
