Finish the sentence :3
You know that you're a nerdfighter when...
You walk up the aisle to the theme from Legend of Zelda (yes I really did, and the organist played it beautifully)
You make an Android app just to keep track of all the kinds of stitches you need to remember for your craft project
Plan your time carefully so you can finish Skyrim before Skyward Sword comes out =^_^=
you are sitting in a movie theater and you see a trailer for Journey 2 and you yell out "OMG! ITS A PUPPY SIZED ELEPHANT! IS THIS ISLAND NERDFIGHTERIA?"
Your friends write DFTBA in your Christmas card.
You currently have three tabs open on your computer: One is the Nerdfighter Ning, one is a vlogbrothers video from 2008, and the other is a PDF of Zombicorns.
...you're at a Christmas party talking about Giraffe sex and honey badgers.
You meet someone truly awesome and think, "He/she would make an awesome nerdfighter".
you start putting things on your head more frequently
...You're talking to a guy, and you instantly know that you can never go out with him, because he didn't understand what the "interwebs" are.
you get all your friends to start hating pennies
when you do a happy dance for using your brain to solve a problem instead of smacking it with the science stick till it works
You know you're a Nerdfighter when you constantly reference Nerdfighteria in conversations even when the other person does not understand what that is. (I do this all the time)
