Actress Wang Luodan the bee's knees on Chinese social media

Mainland actress Wang Luodan is currently best known for her cameo in new Andrew Lau Wai-keung flick The Guillotines.

But this is old news now. Its Wang’s battered knees that have been rising to fame. That’s because the poor starlet has fallen victim to a classic case of "accidental sexual innuendo" gone viral.

It all started when Wang rather innocently posted a photo of her bruised knees onto her Sina Weibo account on Wednesday with the caption, “I’ve always felt this was the only way to show you have ever loved”.

Wang’s said the bruises were a result of injuries from practicing dance moves for a new film project. But netizens did not let such a meme-worthy gaffe off the hook so easily.

As quickly as Twitter-users would have hashtagged “that’s what she said” if this had occurred elsewhere, her post has since been forwarded a staggering 42,000 times across Weibo and has generated a trail of some 18,000 – mostly suggestive – comments about the connotation between bruised knees and oral sex.

“She must have loved…very deeply,” wrote one Weibo user.

“Looks like a terrible case of the carpet knees,” wrote another.

Sensing a marketing opportunity, even condom manufacturer Durex got in on the joke, reposting Wang’s caption on to its official Weibo account, along side a photo of several open condom wrappers.

Durex China seems to have pulled off a relatively decent wildcat social media campaign. Its post has been forwarded over 2,000 times as of Thursday.
