The Official Costume Guessing Thread

[Giraffe]

To keep things organized, because we're obviously all about organization, let's put all the official unmasking guesses in this thread. You can of course speculate and accuse people elsewhere.

Guesses ideally should be like so:

I believe the poster calling themselves 7 and a Half is really

7

If you want to be extra cool, put the clues that led you to their identity in spoiler tags as well.

Please avoid shotgun guessing -- each "official" guess should be matching one costume account to one person. Also, don't be lame about it and post 600 guesses/hour.

Now I'm off to go put on my costume! Woooo!
