Today I want to explain some slang, the phrase "like crazy."

This phrase is often used to replace "a lot" or “very good” or "very bad." Here are a few examples:

Today the wind is blowing like crazy.
今天刮大风了。

It is raining like crazy right now!
现在下大雨了!

That guy runs like crazy, it seems he is always running.
他常常跑步，他好像一直跑步。

She can play guitar like crazy.
她很会弹吉他。

I think I broke my wrist. It hurts like crazy!
我可能坏了我的手腕，它疼死了。

You try it! I'll correct you below :).
