I'm such a spiteful person that I was rooting against the Warriors last night for the sin of losing to the Lakers.
But, I never hated A-Roid for leaving Seattle, or even for being a douche about it. I blamed the shitty Rangers organization for offering him a stupid contract. I still didn't hate him for becoming a Damn Yankee, or for the various things he did like his silly relationship with Madonna. Finally, he got caught in the Biogenesis scandal, and I concluded that his accumulation of douche moves earned him my hatred, and I naturally began calling him A-Roid.
