Whaaaa?

I just read BuddyTV's interview with Sera Gamble (p. 2) in which she uses the terms squick and meta.  These are pretty much fandom only terms, right?  Or am I sadly mistaken?  Does this mean that Sera is a REAL LIVE fangirl?????  Am I the last one in the world to know this?  Inquiring minds want to know!

And yes, the interview is somewhat spoilery.
