An unremarkable term from the 90's meaning a person who is smart turns out to be a loner and is obviously stupid. First coined by Ami Mizuno in the Sailor Moon series.
Ami: Melvin told me about you. He said you thought I would be a total snob.
Serena: It was just gossip. (dreamily stares at Ami for no apparent reason ~)
Ami: I also heard you guys think I'm a Brain Farm Reject.
