Also the word to describe someone heavily obsessed with the Harry Potter books who also happens to be a psychotic know-it-all.
"The one who was correcting everybody because they were saying ridiculous instead of riddikulus?"
"Yeah, she was a real Hermione Granger."
Yea, she is the best character in the Harry Potter series.

Hermione Granger: (snaps her fingers) Hey! She's only interested in you because she thinks you're the Chosen One.
Harry Potter: But I am the Chosen One.
(Hermione smacks him on the head with the newspaper)
Harry Potter: Sorry... kidding!
Best Harry Potter Character for sure.
