It's the newest, and quite frankly the stupidest, social media trend. The whole point of the Charlie Charlie Challenge is to summon a Mexican demon named Charlie.
The challenge is like a cross between the Ouija board and "Bloody Mary" and as silly as it may be it seems like the perfect way to creep out your most superstitious friends.
Here's how it works: Draw a horizontal line and a verticle line on a piece of paper, making sure the lines intersect in the middle. Write "yes" in two opposing sections and "no" in the other two. Then balance two crossed pencils on your paper and you're ready to summon the demons from beyond.
All this time we thought the Cinnamon Challenge was as dumb as it got.
