This vlogger lost a testicle in a new stunt to draw viewers that involved being kicked in his groin if he lost a game of rock, paper, scissors.
Daredevil Will Zeven paid an eye-watering price and ended up losing a testicle.
Will, from the Peruvian capital city Lima, challenged a girl to a game of rock, paper, scissors with the forfeit of a kiss from her if she lost, and a kick in the groin for him if she won. A video of the crunching encounter has become a social media sensation, clocking up nearly 170,000 views on YouTube alone.
After losing the challenge, Will is seen standing with his legs wide open and bracing himself for impact. When it comes, he collapses to the ground in agony clutching his crotch and moaning. Then the girl adds insult to injury when she says: "I forgot to mention that I know karate."
After three weeks of agony, Will finally hobbled into hospital where surgeons told him he had suffered a "testicular post trauma explosion." Ever hungry for viewers, Will got the hospital's permission to film the gruesome op and uploaded it to his YouTube channel.
Although local media covered his modesty with a black dot, the ruined testicle can be seen being dropped into a surgery dish.
He said: "People would call me crazy, but no, the pain was horrible."
Will added: "Nobody was offended and nobody was forced to do something they did not want to do. "What happened to me does not embarrass me, neither makes me less of a man.
"My genitals are still normal, I will be able to have children and sex normally."
The kiss or kick challenge has spread around the world with tens of thousands of youngsters recording their efforts. But Will warned other would-be vloggers: "I want this to be an example for those people who want to do the challenge - take precautions."
