I wonder if they even know what they are yet. They're still in an earlier Freudian stage (probably anal), where they think it's their duty to do weird things in order to provoke people, as opposed to expressing anything honest about who/what they are. The decided attachment to Britney is a telltale sign, sort of like Rosie O'Donnell always professeing her love for Tom Cruise before sahe came out: it's a dated, archetypical choice that never gets updated based on who the object really is.
Maybe John's growing out of it quicker than Edward.
Ultimately though, they are total mo's. Oh yeah. Bank.
