The fainting game, also commonly known as the choking game, is a loose term that covers angerous activities designed to induce a partial or complete loss of consciousness brought about by the intentional deprivation of oxygen to the brain for a period of time. There are two distinct methods used to achieve oxygen deprivation: strangulation and self-induced hypocapnia. Many teenagers do it to show off in front of their friends, but what they don't know is that it can kill them.
