Here's a pretty simple rule: Don't cheat on your significant other.
However, if you feel absolutely compelled to cheat -- say, for example, an eco-terrorist in protest of how our government is treating the “wood” of the world has attached a bomb to your head that will detonate unless you have sex with a bunch of people who aren't your girlfriend -- please, for God's sake, try not to get caught.
Getting caught cheating is simultaneously the cruelest and dumbest thing you can do, and publicly shaming someone for doing it seems to be one of the more common strategies for people who've been slighted.
What's the worst way to get called out? Social media. After all, people have been horrible, cruel morons forever, but now we have the Internet to permanently preserve their idiocy for generations.
Here are a few of the dumbest examples. Shall we begin?
I mean listen, the guy plays guitar. That's just cool.
