Batmanning emerged in 2011 as a successor to the Planking and Owling crazes, challenging participants to hang upside down by their feet from ledges, doors, or rafters. This 'vertical planking' was inspired by the iconic hanging pose of Batman and quickly gained traction on platforms like Facebook and YouTube. While physically demanding and occasionally dangerous, the trend became a staple of early 2010s internet culture, often used to show off athleticism or simply to create a surreal, gravity-defying image. Today, it remains a nostalgic reminder of the era of viral physical challenges and the internet's obsession with the Caped Crusader.
