THE latest craze to take over Twitter has participants trying to summon a Mexican demon called Charlie using an Ouija-board-style ritual then posting videos of their experiences online.

Said by some to be an “ancient Mexican tradition”, the so-called CharlieCharlieChallenge requires positioning two pencils on top of one another to form a cross on a piece of paper. The words “Yes” and “No” are written on each of the quadrants formed by the pencils on the page.

Participants must then ask: “Charlie, Charlie, are you here?”

If Charlie is present, the pencil will point to “Yes”, and you can proceed to communicate with the popular demon through yes/no questions.

Many are using this one-on-one chat session with the spirit to ask him relationship advice — while others are hoping for an answer to some of life’s big questions, like when Justin Bieber will release his next album, or which One Direction band member they’ll marry.

Participants have been told to beware.

According to Twitter lore, when it comes time to wrap things up, you must say goodbye to your demonic friend by chanting “Charlie, Charlie can we stop?” Failing to do so may result in other demons coming into your home.

“These demons that are being contacted may seem friendly at first,” one Twitter user posted, “but they have sinister plans.”

“If you do not say goodbye to Charlie, you will experience paranormal situations as in hearing voices, things being moved, shadows, sinister laughing and more,” she warns.

The laughter, however, seems to be coming from other Twitter users and sceptics rather than anything supernatural.

So the real question is: Is this just a fad or something more disturbing? Maybe Charlie has the answer.
