Cockroach problem is a problem that is bigger than it initially appears.
蟑螂问题指的是比原先看起来还要严重的问题。
You've got one little piece of bad news, and there is always more, just like those little bugs.
你先是收到一条坏新闻,然后坏新闻源源不断地接踵而来,就像那些烦人的小虫子一样。
请看例句:
If you solve the problem earlier, it won't be a cockroach problem.
如果你早点解决这个问题,它就不会比原先还要来得严重了。
