An almost-OCD disorder (or, some would say, "passion") in which a person is constantly attracted to any girl named Sarah, regardless of how bitchy or annoying they are. Made famous by "Paqrat" from the pop-punk band Way With Words (myspace.com/waywithwordsband)
"Dude, she called you a stalker, gave away the rose you gave her to some random girl, told all her friends she would call the police if you talked to her again..."
"I know but she's SARAH. And I have a Sarah fetish."
"...whatever, man."

"Dude, if you don't like that girl at all, why are you going out with her?"
"It's not hard to figure out. I have a Sarah fetish."
