Nobody wants to get cheated on by a significant other, but if or when it ever happens, one of the most important decisions you can make revolves around how you're going to retaliate.
You can take a course of action that results in an attempted murder charge or a hospital visit for alcohol poisoning, but if you really want to get revenge, it's best to take the higher road.
I'm not an expert by any means, but I'd say that the unidentified man who was forced to deal with a girlfriend who'd been cheating on him for two years took a pretty good approach.
It's worth mentioning that a blacked-out Facebook chat featuring the cheating spouse of a nameless friend getting his comeuppance is literally the first thing I'd make if someone held me at gunpoint and told me to create a picture to go viral.
But I guess it could happen in real life.
