The Choking Game
The NYT gives a big writeup (Teenager Casts Light on a Shadowy Game) to "the choking game" (also known as The Fainting Game, Airplaning, Dying game, Sleeper Hold, Space Cowboy, Space Monkey, Suffocation Game, Suffocation Roulette according to Wikipedia). It's nothing new, but may be spreading (isn't everything?) via YouTube. Click below for a news video about a San Antonio student who died doing it.
