Can you touch your belly button? No, not that way! Touch your belly button by first wrapping your hand around your back and then reaching around your side to the front of your stomach.
That's the "Belly Button Challenge," which is all the rage on the Chinese social network Weibo. According to the BBC, the Belly Button Challenge has sparked over 104,000 discussion threads with over 130 million mentions.
As you can imagine, the topic is popular amongst the young female users on Weibo (the Chinese name of the trend translates to "reaching your belly button from behind to show your good figure.")
But in case you think that only skinny girls can beat the Belly Button Challenge, a rather plump young man rose to the occasion and posted this photo, with the comment "Is this trend really that difficult? I don't think so."
One commenter said it all. "You go Buddha! Show the skinny girls how it's done," replied a Weibo user.
