An old Mexican game has become this week's Kylie Jenner lip craze – dominating social media and spooking just about everyone into a frenzy.

And while there are no reports of the Charlie Charlie challenge resulting in bruised and bleeding lips, it's definitely just as captivating as its predecessor.

It involves nabbing a friend, and drawing a horizontal line crossed with a vertical line on a sheet of paper, writing 'yes,' and 'no' in the resulting squares. You next balance two pencils into a cross shape over your illustration.

In tandem, you and your friend then ask aloud: “Charlie, Charlie, can we play?” If the top pencil tilts upwards or inwards, then the mythical being that is Charlie wants to have a chat. If nothing moves, then he's not feeling particularly sociable. 

Millions have lately been trying out the craze; leading to some seriously terrified (not to mention hilarious) responses – and all captured on video too. 

Predictably, some social media users have adopted a more light-hearted approach, asking, for example, if Justin Bieber will release a new album this year, or if they should have pizza for their dinner. 

One Direction fans have even been placing the faces of each of the four members of the boyband in the squares instead of 'yes and no', subsequently querying which one they'll end up marrying.
