"Duang" has now become one of the hottest hashtags on Sina Weibo, a Twitter-like Chinese social networking site amid a frenzy of posts imitating Jackie Chan's speech in different scenarios.

The actor's Weibo account was flooded with comments containing the word in this sweeping online trend.

The video came at a time when the renowned movie star has been under public scrutiny after trying to salvage the drug scandal-tainted image of his son, Jaycee Chan, who was released from prison this week.

Data from Baidu also proved the phrase's popularity as it has been searched more than 586,000 times as of Thursday on the major Chinese search engine.

It's not the first time that online slang has invaded the regular lexicon in China.

The word of gei li's sudden rise in 2010 caught the attention of international media when it coined the word's official translation – gelivable – to describe something cool or awesome.
