Blac Chyna Teaches A Weird How-To On Instagram

Blac Chyna and Rob Kardashian are all over social media. It isn't just all fast cars, baby bumps, and emoji, either. Chyna got into the how-to business on her Instagram. The soon-to-be Mrs. Robert Kardashian posted a video with instructions on how to do a weird trick with your tongue. "First, you stick out your tongue. Then, fold it two ways." Okay, that sounds simple. It also looks weird. A lot of people believe that tongue rolling (or folding, or whatever-ing) is a genetic trait that only some people carry. Not true, according to PBS. Whether you can do it or not, Blac Chyna is here to help you try.
