The trend, which went viral Monday on Twitter, features participants placing a pencil across another in the shape of a cross on a piece of paper with the words "yes" and "no."

Some users said the ritual must end by asking "Charlie, Charlie can we stop?" so the "demon portal" is closed. There is also a six-pencil variant of the game that requires at least two people.I tried staying calm & thought it was wind but then the second time I freaked, I'm shaking #charliecharliechallenge pic.twitter.com/Srih2n4b6L— zhenjiang skye (@WifiCollins) May 24, 2015 The "Charlie, Charlie Challenge" hit U.S. social media during the weekend, but has been circulating Spanish-language websites for some time.
