Batmanning, the latest 'position craze' spreading among netizens, draws its name from the nocturnal mammal which inspired the superhero.

Batmanning, as demonstrated in the viral video, involves suspending oneself upside down in a rather awkward location.

A group of young men, calling themselves the Batman Boilers, came up with the daredevil sport challenging the likes of popular planking, owling and horsemanning.

The video shows people performing the stunt as the Batman theme tune is played in the background.
