Why the sudden rise in usage of "吓死宝宝了"? 吓死宝宝了


All of a sudden this "phrase" (if we can even call it that) is everywhere. I'm reading it, hearing it and seeing it everywhere.

What gives to the sudden rise in usage of this expression?
I think it's because of the Internet, which made this sentence popular. There was once a boy in Sina Weibo (China's version of Twitter) who sent a threat to a girl. The girl on Sina Weibo replied to express her dissatisfaction. The message was "吓死宝宝了". 

It soon got around on Weibo. Many people were talking about this. So now many people use this sentence to express their discontent by force or threat.
