I've found in the Net some other dangerous things that North American teenagers do. Here you are:
1. Helmet boxing. Is an underground sport that's just beginning to surface. To play, each individual dons a helmet with a face mask, along with a pair of gloves, and then each hits each other in the head until someone passes out, a helmet gets knocked off, or someone simply throws the towel. Doctors are warning that even though they are wearing helmets, they are still at risk for bodily harm.
2. Ghost riding. It's not fast or furious, but a new phenomenon known as ghost riding -- leaving your car in motion while getting out to dance -- is quickly becoming the latest craze among some members of the hip hop culture.
Usually on a residential street, a driver and any passengers jump out of a slowly moving vehicle to dance beside or on top of their "whip" (hip hop slang for car). Then, as the car drifts away, the driver runs back to the vehicle and regains control.
Popularized in the song "Tell me when to go" by California rapper E-40, the act spawned from the Hyphy Movement -- a style of music and dance that emerged from the San Francisco Bay Area's hip hop culture.
The popular rapper chants "Ghost ride the whip," and most of the videos posted online of ghost riding are accompanied by the song.
Popular video websites like YouTube have hundreds of clips of ghost riding where teens attempt the stunt on suburban roads, open fields, parking lots and even on the freeway.
While street racing has been aroung for a long time, getting out of the car adds yet a whole new risk to the subculture. Police have blamed at least eight deaths on ghost riding and they have developed their own name for the fact. "The only name you can give it is stupid", said one officer.
3.Car Surfing, a new craze fuelled by pictures of stunts on the internet, has claimed its first British victim.
An 18-year-old man from Chesterton, near Harbury, Warwickshire, died in hospital after toppling from the roof of a Fiat Punto on Tuesday night. His name has not yet been released. The car’s 18-year-old female driver was arrested.
The victim is the first Briton to have died from a trend that originated in America and has spread in the past year with the growth of websites such as YouTube, on which car surfers post footage of their antics.
At least two other people have suffered head injuries in the past few weeks in British car-surfing incidents, in which teenagers stand on or cling to the roofs of moving cars. Many incidents have been reported in southwest England, with beaches a favourite location. Other incidents have been recorded in Suffolk and on the Isle of Mull.
One youth from Exmouth in Devon – named locally as 17-year old Greg Barton – is still in a critical condition in hospital after falling off a moving car. Chief Inspector Ian Aspinall, head of road traffic at Devon and Cornwall police, said car surfing was part of the “boy-racer culture”.
“This is the first time we’ve had a serious injury caused by car surfing,” he said.
The craze has its origin in the “hyphy” culture of the west coast of America, whose proponents listen to gritty urban music with pounding rhythms, and pride themselves on adrenaline-boosting stunts. It follows the equally dangerous craze for train surfing.
British car surfers, like their US counterparts, say it gives them a huge adrenaline rush. But the phenomenon claimed three lives in America last year.
