O_o um.... sorry, that's just something innate with humanity and has been on the internet since forever. It's humankind's big quest to see who the biggest jerk on the block is. It's why the Nazis back in the 40s didn't look at each other and admit that this whole thing had gotten out of hand more than a little bit, and look at the size of their shoulder pads, for the love of God. It's why Stalin saw to accumulating the majority of war time casualties back in WW2, and then immediately turned around and executed some more of them. Everything from Enron to partisan politics, from ancient gladiatorial combat to monday night RAW, it's all to serve the ideal of winning and proving that the other guy is less than you, because being a jerk is just one of the small handful of things that we humans do.
