facebook fonies 

hipsters who are too ' hip ' to publicly announce their facebook profiles, but who secretly own an account and spy on their peers to purloin ideas since the hipster possesses no originality.

Sh-iii-t, facebook fonies are all the same; they lie about not being on-line all-day but secretly gather intelligence on the freshest trends out there like Aliza who uses her Yale buddy's email account to parrot stolen information to her decrepit and doddering professors in New Haven.
