Annoying pre-teen girls who are obsessed with the Jonas Brothers, Hannah Montana, and all those other so-called "musical artists."

The definition of sell out. A highly overrated band with a horrible vocalist who cannot sing for his life. Pete Wentz is the only member of that band who gets any credit and i'm sick of hearing little teeny boppers talk about how "hawt" he is. It makes me want to barf. He looks like a monkey with eyeliner. I bet all 13 year old girl Fall Out Boy fans now despise Ashlee Simpson.
