FSM

Fangirl soul mate. Someone you've met (most of the time online) who seems to fangirl over the EXACT same things you do, almost like you're the same person!

I was talking about Fringe last night with a girl who had the exact same opinions on the show as me - we're fangirl soul mates!

My FSM and I spend all last night freaking out over the Rizzoli & Isles season finale
