From Rebel Chris in Vegas (who passed this along, because there was no way that I was going to read it).
Of those five hater theories, only No. 4 applies to some degree. But there's a huge difference between being perceived as a hater and actually hating someone. The hater gimmick sprung from the Internet, where bloggers and message-board posters rip people to shreds on a daily basis. It's a logical tactic: If you want to cause a splash, but you're not talented or funny and lack an interesting take, what's left? You attack. As those attacks turned more and more venomous, the most common counter to them became, "You're just a hater."
Emphasis mine ... now you read that line and you think of Ara Parsegian in Rudy when he tells Vince Vaughn's character that he has summed up his lousy career in just one sentence as he's gone from the third string to the scout team.
