Duang

The completely made-up onomatopoeia took Chinese Internet by storm since appearing online on Feb 24, and generated hundreds of thousands of hashtags and conversations.

It turns out that the character was created by Jackie Chan describing the particular effects of Bawang organic shampoo in a commercial back to 2004. "Make your hair go 'duaang' Very black! Very shiny! Very soft!" Chan says in the ad.

Because there was no existing Chinese character for the buzzword, some creative Internet users stacked the characters for "Jackie" and "Chan" to represent duang.
