Horsemanning, or fake beheading, was a popular way to pose in a photograph in the 1920's. Sometimes spelled horsemaning, the horsemanning photo fad derives its name from the Headless Horseman, a character from “The Legend of Sleepy Hollow.”
The object of horsemanning is to make it appear that the photo's subject has been beheaded, like the Headless Horseman. Typically, one person lays with their head hidden while the other exposes only their head in the photo. If done correctly, horsemanning produces a brilliant optical illusion and allows for more creativity than other photo-posing fads like planking. Also, while planking is a solo game, horsemanning /horsemaning encourages social interaction as it requires a partner.
