I grew up mostly before the internet and we did lots of stupid things as kids, including this exact black out stunt. What I think social media has done though is push people beyond their normal internal brakes. You and your friends might push each other to do risky things, but friends tend to care about one another internally. Anonymous people on the internet don't know you or really care about you, so it's easier for them to push people into riskier situations.
